Hi,
after your announcement on Helix 3 compatibility with J6, I tried to install the quickstart package for Rhino Template, but when accessing the admin I got this :
An error has occurred. 0 Class "Joomla\Plugin\Behaviour\Compat6\Extension\Compat6" not found
Any idea where it comes from ?

Accepted AnswerHello,
Sorry to hear that and Thanks for the response.
I have just tried the quickstart on my local to check and it works fine.
Kindly, check the screencast in the hidden content box.
You may also recheck the technical requirements from the below link:

Accepted AnswerHi,
Thank you for reaching out.
The error:
Class "Joomla\Plugin\Behaviour\Compat6\Extension\Compat6" not foundusually indicates that the Joomla Compatibility plugin/files are either missing, disabled, or not installed properly.
Please note that although Helix3 has compatibility support for Joomla 6, older quickstart packages/templates may still contain dependencies or plugins that expect Joomla backward compatibility layers to be available.
Could you please check the following:
-
Make sure the Joomla installation completed successfully without any missing files.
-
Go to your System>Manage>Plugins and check whether the Behaviour - Backward Compatibility 6 plugin enabled or not:

Kindly do let me know if it helps!

Accepted AnswerHi,
thank you for your answer.
- According to filezila, all files were successfully transfered to my server
- I can't navigate on my admin panel (no menu or anything), so I checked directly in the database if the backward compatibility plugin is enabled (or missing).
- Checking in "extensions" table, I can only see plg_behaviour_taggable and plg_behaviour_versionable, but nothing else. I suppose I should see plg_behaviour_compat6, am I right ?

Accepted AnswerHello,
You are welcome.
Did you follow the official Joomla 5 to 6 migration guide below, please?
Joomla 5 to 6 Planning and Upgrade Guide
If yes, then according to my understanding, the Behaviour - Backward Compatibility 6 plugin should be available there.
If the plugin is missing or the upgrade process did not complete properly, you may try restoring a backup first and then perform the Joomla update again by carefully following the recommended steps in the guide.

Accepted AnswerHi,
I did a fresh install, not an upgrade. I downloaded the Quickstart Pack Joomla 6 you provide on the Rhino Template page here : https://www.joomshaper.com/joomla-templates/rhino Then upoaded the files to my server and followed the Joomla installation process, as I already did for many websites. At the end of the intallation, I logged to the admin panel and found the error message I showed you. I did nothing else. Should I erase files & database from my server and try again an installation of the Rhino Quickstart Pack Joomla 6 ? I would like to be sure there is no problem with your pack before :-)
