I hope this is the right place to address this issue:
Joomla 5 (latest)
Editor: JCE
When editing Joomla Articles from frontend, then in CUSTOM FIELDS the editor-button shows, but the content (articles, templates, tips etc.) aren't placed in the field when chosen.
When using the editor-buttons in the article itself, it works.
Can you give me (super) admin and (s)ftp access so I can take a look?
And tell me how to see/reproduce the issue.
You can use the 'Confidential information' button in the forum editor to hide sensitive information.
All your 3rd party editor buttons are not working (Engagebox, Jfilter). It is not just the Regular Labs buttons.
Nothing I can help you with.
Probably a template issue.
