J5 to J6 - Deactivation of Backward Compatibility failed

Buldre

Hello,

I am using JA Magz II version 2.2.0 with T3 version 3.3.1, and will now update Joomla from 5.4.1 to Joomla 6. The update requires that I first deactivate Joomla "Behaviour - Backward Compatibility", but deactivation breaks my website

I have now found that the problem is related to the JA Magz II template. When I switch to Cassiopeia, the website works fine with backward compatibility deactivated.

These are error messages I have found on the website after disabling Backward Compatibility:

Class "Joomla\Component\content\Site\Helper\RouteHelper" not found

Class "JLog" not found

Do you have a fix for this?

Buldre Hi

Behaviour - Backward Compatibility plugin is required for template work properly in J6. Could you please switch to Cassiopeia >> migrate site to J6 >> then enable Behaviour - Backward Compatibility again when switch back to JA Magz II template?

Thanks! I took the chance to try your suggestion, and it worked! But it was not necessary to enable the old Behavior - Backward Compatibility, as it disappeared during the migration process, and the new Behavior - Backward Compatibility 6, was already enabled.
