Known PS / UXP Issues (affecting my panels)

The purpose of this page is to provide information on known issues which have not yet been fixed (these will typically be issues in Photoshop / UXP, as I otherwise tend to fix known bugs in my code very quickly - unless they are very difficult to reproduce).

Note that this list assumes you are running the latest version of Photoshop. Bugs which have been addressed by Adobe will generally be removed from this list fairly quickly.

Known issues (anything marked as UXP-related means that a Photoshop update will probably be required to address the issue):

  • PS error message "could not complete the Duplicate Layer command because of a program error." This affects PS on Windows with the latest beta PS. This appears resolved in the latest beta build (m.2471 - check Help / System Info and look at the end of the PS version). If you still have issues, use these workarounds: Use the regular version of PS, or fall back to an older version of PS by clicking "..." next to PS in the Adobe installer and choosing "other versions".
  • The Adobe installer reports that there is "no compatible app" when double-clicking the CCX. Workarounds include:
    - Make sure you have at least PS v24.2 installed (current minimum for Lumenzia v11 and Web Sharp Pro v5)
    - Make sure the Adobe installer shows PS itself as installed (there is a bug where it may forget and require PS to be installed again). You may click to install PS again (it will overwrite PS prefs, so you may wish to back up first, or run flyout / Utilities / Optimize in Lumenzia or WSP).
    - Try removing any PS beta you have - this has caused conflicts in the past for some people.
  • None of the buttons work. This may be caused if file permissions are corrupted for plugin data (which may occur after some PS updates). Workaround: Uninstall and re-insall the plugin (go to Plugins / Manage / ... to uninstall). You may wish to first backup the plugin data, as uninstalling will reset all panel preferences / templates. The folder can be found in:
    - MacOS: /Users/
    {yourUserName}/Library/Application Support/Adobe/UXP/PluginsStorage/PHSP/25/External/_____/PluginData
    - Windows: C:\Users\
    - Where PSPH may be BETA for PS beta, the number will be the major version of PS you're using, and ____ will start with 0a4b for Web Sharp Pro, 3ecc for Web Sharp (free panel), dddd for Lumenzia.
  • "Map" button in Lumenzia does nothing, and you may see PS errors until you click "X" to clear the preview layers. This is a known bug in PS v25.1 (and the v25.2 beta). Workarounds fall back to PS v25.0 or the final v24. Click "X" to clear the Map preview layers if you need to save your image.
  • Lumenzia previews (such as D2) run extremely slowly. This is a known bug in PS v25.1 affecting performance of adjustment layers and brushes. Workaround: fall back to PS v25.0 or the final v24.
  • Panel is not visible after installing or launching from CCD. This is a known MacOS bug which has been reported to Apple. Workaround: click <TAB> twice to hide all panels and then show again, or go to the Plugins menu in PS to hide and reshow the desired panel.
  • Vertical text alignment for Lumenzia buttons are spaced out or significantly off-center. This is a rare PS bug specific to Windows. The underlying issue appears to be use of some 3rd party fonts. I am unclear exactly why these fonts cause conflicts with UXP and whether the fonts may be updated to avoid this or if a future PS update may be able to resolve the issue. Users have reported conflicts with a few different fonts (several have reported conflicts with Anthoni Signature from DaFont, one person reported Amalfi Coast from DaFont, and one person reported Anisha Modern from Envato). I am unclear what the common factor may be, but it would appear that several fonts might trigger this issue with the current versions of Photoshop.
    Workarounds include:
    - Best option: Remove the conflicting font. You can move all possible fonts out of the installed location and restore them in groups to help quickly find the responsible font. Restart PS after any font changes. Or you could try to
    reset all fonts to defaults (be sure to back up your fonts first). Note that resetting fonts may not work, as this does not necessarily remove 3rd party fonts.
    - Alternative if the font fix fails: Go to the flyout menu in my panel (top-right three bars icon) / Utilities and look for a couple options in the right-hand column to help fix alignment. This is quick and easy and avoids the need to remove fonts, but does not resolve the issue for all users (probably either depending on the font, or the possibility that there are triggers other than fonts for this issue).
  • Dropdowns do not work. This is a rare issue, which appears specific to Windows. Potential workarounds:
    - Click on the dropdown, then use arrow keys, then click <space> to choose the option (you won't see it, but using arrow keys should still help select from the hidden options). You may have to try a few different variations of arrow keys to know you're not' selecting the same item blindly, so try up and down separately.
    - Try right-clicking a button in the main panel a couple times to toggle tooltips, this may reset the behavior where PS is hiding the dropdown behind the dialog.
    - Another potential workaround is to use File / Open in PS, which may also reset the behavior in PS.
  • Error message "The command Make is not currently available". This is a bug in PS where it refuses to create a group for layers under valid conditions. Once the issue is triggered, it will happen over and over until PS is restarted. Ultimately, a PS fix is needed but you can workaround it. The issue appears to only affect Windows users. Workaround: Update to PS v23.5, which fixes the issue. Or save your work and restart PS. The issue is rare and should not happen often, unless you do not restart PS (and then it will happen repeatedly until PS is restarted).
  • The panel will not start. This may be caused by 3rd-party programs which interfere with normal operation of Adobe software Workaround: try disabling any such programs which may limit software (check firewalls, anti-virus, cleaning tools, etc for any interference with Adobe software).
    CCleaner has been reported to interfere with installation, you may wish to approve CCXProcess or disable CCleaner (or at least it's "
    Performance Optimizer" which can put background programs to sleep) and try installing again.
  • The panel will not start. This may be caused by PS being unable to write to data folders (probably some kind of permissions issue in Photoshop, CCD, or UPIA which is not showing any clear error for the user). Workaround: close PS, delete the PS folders for panel data, and restart PS. This will allow it to regenerate folders with proper permissions:
    - On Mac, click <cmd>-<shift>-<period> to show hidden folders and navigate to /Users/ {{ your user folder }} /Library/Application Support/Adobe/UXP/PluginsStorage/PHSP/23/External
    - On Windows, navigate to C:\Users\ {{ your user folder }} \AppData\Roaming\Adobe\UXP\PluginsStorage\PHSP\23\External
    The "AppData" folder is hidden on Windows, so either paste this location into the File Explorer (be sure to update the user name), or go to the view options in the file explorer and make sure "hidden files" is checked to see it.
    - Move the contents of this "External" folder somewhere else (such as to the desktop, so you can restore later if desired) and then delete the External folder. "External" is where Adobe puts all the 3rd party data for UXP plugins, and it will contain one or more strangely named sub-folders for each panel
    - The "
    dddd1010" folder is for Lumenzia, "0a4bb5cd" folder for Web Sharp Pro, "3ecc70be" for the FREE free version of Web Sharp.
    - After deleting that folder, restart PS and the folder should be recreated (but this time with proper rights and the panel should work). If it still does not work, try deleting at a higher level (such as the 23 or PHSP). PHSP is a reference to "Photoshop" (as opposed to other Adobe applications which would have other 4-letter designations). The number "23" here is for the version of Photoshop, which is one greater than the year (v23 is PS 2022, etc). So this link would end in 24\External, 25\External, etc for future versions of PS.
    - If still failing, be sure to check that you don't have any anti-virus or other defensive software which may be blocking Photoshop's ability to read and write these folders.
  • The plugin is missing from PS (even though showing as installed in the Adobe installer, CCD). Please see below for possible fixes.
  • An error message referencing "Unimplemented method: getNativePath". This is a permissions issue resulting in a misleading error, you should rename (to hide but preserve the data in) the following folder and restart PS (this will reset all plugins to their default state): /Users/ {{ your user folder }} /Library/Application Support/Adobe/UXP/PluginsStorage
  • A progress bar may appear while you are supposed to be working interactively with the panel (such as interactive cropping, responding to a dialog with options, entering an interactive radius for sharpening, Color Range, Content-Aware Fill, etc), resulting in the interface appearing to be stuck or unusable. This is a UXP bug requiring an update from Adobe, unresolved as of PS v23.1. Workaround: Click on the dialog (not the progress bar) to put focus on it. This will generally allow interaction with visible elements (Sky Replacement is very limited if you have selected a sky as the dropdown won't close), as well as ability to click <ESC> or the red X to close a popup without having to force-quit Photoshop.
    If truly stuck, please sampling the Photoshop process on MacOS ( or get a process dump on Windows: ( and send to me to forward to Adobe for review. This information can show the developers where things are getting stuck.
  • Photoshop shortcut keys are ignored after clicking a button in a UXP panel (you may hear Photoshop emit a beep to indicate that it rejected the shortcut key). This only seems to be an issue if the panel is floating. If you "dock" it (where it has a permanent position in a column at the side), it seems to be fine. Workaround: Either dock the panel, or click anywhere in Photoshop (other than the menus) after using the panel to restore focus to Photoshop so that it will respond to shortcut keys. Alternatively, downgrade to PS v23.1. ***
  • Cannot type in opacity / fill values. This is another manifestation of the previous UXP bug. Workaround: Instead of typing opacity values directly into the text box, just click the numbers quickly without clicking into the text field (ie 4 then 5 as a shortcut for 45%). For fill, hold <shift> and click the number. Or skip the keys and click and drag on the word opacity/fill (use the "scrubby slider"). Hold <alt/option> to slide in smaller amounts.
  • The color gradient behind the DML buttons in Lumenzia may not show any change or just partial update when clicking the color swatches at the top or clearing them. This is a UXP bug requiring an update from Adobe, unresolved as of PS v23.1. Workaround: move the mouse outside the panel, this seems to cause the interface to update properly.
  • Lumenzia v9 and older: Marching ants are not hidden as requested. This is a Photoshop bug in PS 2022+.Workaround: update to Lumenzia v11, which is not affected.
  • G-Bench fails auto-align test for some users. This is a UXP bug requiring an update from Adobe, unresolved as of PS v23.1.Workaround is built into latest G-Bench (allows you to skip this test), including G-Bench in the latest versions of Lumenzia and Web Sharp Pro.
  • Adobe's list of known UXP issues may be seen at
  • Note that if any of the above workarounds are insufficient, you may also install Lumenzia v9 as a workaround. While v10 has added some new features, the focus is on UXP migration and v9 is an excellent alternative (v9 requires Rosetta for M1 users).

*** To downgrade Photoshop: Open the Adobe Creative Cloud Installer / All Apps and click ... next to Photoshop for "other versions" to install and older version.

If your plugin is installed in CCD but does not show in the Plugins menu of PS:

  • First, look under the "Plugins" menu of PS, where the newer UXP panels are found. [Note: Windows / Extension (legacy) only applies to older CEP panels. All of Greg's panels are now available as UXP panels and this panel is only meant to provide support for the UXP version of the panels.]
  • Please check that you are running a version of PS which supports the minimum requirements for the panel (Lumenzia and Web Sharp Pro currently support v23.0, but will soon require v23.3). The easiest way to check is to update to the latest version of Photoshop and make sure you are launching that new version (you can have older years of PS installed at the same time). Look under Help / System Info to confirm the version of PS.
  • Try repairing CCD ("Creative Cloud Desktop", same Adobe installer used to update PS itself). Next to CCD should be an uninstall program. Run that and choose the "repair" option (no need to uninstall it).
  • Try reinstalling the plugin. This may reset all plugin data (causing loss of any custom settings or templates), so be sure to back up your plugin data first. Go to the top-right flyout menu in Greg's plugin and choose Utilities / Export panel data to create a backup. Once you've backed up, go to Plugins / Manage in PS to show installed plugins in CCD, then click ... to uninstall, and then install again normally (using the CCX from the ZIP download for Lumenzia or downloading from Adobe for Web Sharp Pro).
  • If still stuck, please contact [email protected].

Photoshop beta (help get bugs fixed!)

If you are affected by a bug in Photoshop, one of the best ways to help ensure it gets resolved quickly is to participate in Adobe's beta program. This is VERY easy to do (no more complicated than downloading any version of Photoshop, and it is separate from your official version of Photoshop so that you can launch either and avoid any problems you find in the beta).

Install the beta simply by opening the Creative Cloud Desktop (CCD) app (where you install and update Photoshop normally), then go to the "beta apps" section of the list on the left to install the Photoshop beta. You can watch a video of the steps here:

Note: Be sure to enable automatic updates for the beta. In CCD, go to preferences / apps and make sure you see the blue toggle on Photoshop (beta). New releases come out roughly every 2 weeks.

You can provide feedback directly to Adobe engineering from the beta by clicking the "beaker" icon at the top-right of the beta.
