Bug confirmed

I have the same problem under 5.2 and cannot edit existing articles either via the backend or the frontend. However, I have neither changed the standard image directory under Plugins System File System, nor do I have Phoca Download installed. The template is Helix Ultimate. This is very problematic, as I had no issues under 5.1.4. What additional information is needed? Here is the debug-info:

This appears to be the result of the changes made in #43579

I can replicate the bug and if I revert the changes in that PR the bug is cleared.

Hope that helps someone to resolve the bug

It is not very clear how to reproduce the error.
After update to 5.2 TinyMCE works, drag&drop upload works, for me.

I found it can only happen when "Media: Options" => "Path to Files Folder" field contain folder that not in the plugin "FileSystem - Local", and "Images Directory" in the TinyMCE plugin is empty.

Can someone confirm?

To fix this error on your site, please make sure the folder in "Media: Options" => "Path to Files Folder" also choosen in the plugin "FileSystem - Local".

It is strange behavior of Media manager, in

The #43579 uncovered this bug.

To fix this error on your site, please make sure the folder in "Media: Options" => "Path to Files Folder" also choosen in the plugin "FileSystem - Local".

That only partialy works. If you select a root folder eg plugins in the filesystem-local then you have to select a subfolder of plugins in tinymce. Leaving it empty in tinymce does not default to the plugins folder and still gives the error,

Either way thats not a real fix just a temp fix until code can be fixed and released.

If you select a root folder eg plugins in the filesystem-local then you have to select a subfolder of plugins in tinymce.

Let say you have folder files. Then you have to:

• Edit Media manager global options, set "Path to Files Folder" to files
• Edit plugin "FileSystem - Local", and select files there.

Then TinyMCE will work even with empty value, all upload will be directly in to files/ folder.

Either way thats not a real fix just a temp fix until code can be fixed and released.

Yeap.

it did not work for me with the empty as you described

@Fedik I know thanks, but thats no option for me. I hope for fix.

Please test #44313

Your solution in #44313 works only in Backend, Frontend still the same error.

This also happens if the Path to Files Folder or Images Folder has an uppercase.
