Hello,
I fixed that.
However, when I tried to create a test module in the position left and right (to test the columns), I saw that I couldn't. Try to create a custom Joomla module, and you will see the error. Also, this causes the error in the template files every time you save the template settings.
This error is not caused by our or any other template.
This Joomla installation is obviously broken, probably due to an improper upgrade from Joomla 3 to Joomla 4. You should start a brand new Joomla installation (use HotStart template installation method) or upgrade from Joomla 3 again (we can upgrade it for you as a paid job).
Sorry, but I can't help you with this Joomla installation anymore.
Regards,
Milos
