But then, after the update to Joomla 4.2, things go wrong. and I see one error after another. I don't know PHP and I can solve some small issues but not the big problems. I also ask myself whether solving that "one error" is really the solution or whether this will lead to the next error.
I also installed the updated Arino template in the Joomla 4 environment. Complete with the Arino_settings.sjon. But unfortunately this was not the solution. Not even when I try another Jooomshaper template that is Joomla 4 ready.
