Hello,

we try to upgrade website from Joomla 3.10.12 to 4.4.9.
before upgrade of joomla I updated Flexi
to the latest available version : 4.2.1
All works fine on joomla 3.
In joomla 4 everuthing seems to work for category lists but accessing a single item gives the below error. This as well from a direct menu item as from a listed item of a category.

Any idea what went wrong?

Kind regards

Geert

found the origin: templates contained some custom coding that are not compatible with J4.
