Hi,
we’re running request tracker 5 from Debian and the wysiwyg editor stopped working after updating to Firefox 148.
I found that the problem is related to 2002481 - Latest nightly versions seem to have broken CKEditor 4
The ckeditor shipping with RT has the version set to “DEV”, so the workaround they put in place is not triggered.
One can check that by opening the developer console on a page with the wysiwyg editor and looking for the value of “window.CKEDITOR.version”.
To fix this in our installation, I copied the ckeditor.min.js file (located at “/usr/share/request-tracker5/static/RichText/” on Debian) to the override directory (“/usr/local/share/request-tracker5/static/RichText/” on Debian) and patching it to have version=”4.DEV” instead.
After clearing the mason cache and restarting the editor was working again.
Hope this helps someone.
