Joomla Upgrade To Version 4
elsmachimo
hi, before I updated from version 3 of joomla to version 4 i verified all addons for compatibility and all checked out but after upgrade when I try to access pages built with pagebuilder I now get the error message
"An error has occured Error: 0 jmodle class not found " and cannot access any pages to edit in backend or frontend.

Accepted AnswerHello elsmachimo
Apology for the inconvenience. Please share your CORRECT administrator access here to check the issue. Use the Hidden Content box to share the credentials. Make sure that you have a full site backup with you before sharing.
Best regards

Probably one of installed extensions is not Joomla 4 ready, I will check what can be.

Accepted AnswerFixed. You had installed JCE editor for Joomla 3.x only, very old version, from 2019 (!). I uninlstalled it, and now is 100% OK in admin area.
Please download and install the latest version of JCE editor (v2.9.22).
Next time before Joomla upgrade check if you installed new versions of all used extesnions, do not trust only Joomla tester, trust yourself. You're welcome. Have a nice day.
