This is my first posting in this forum. I do have a problem with updating my Joomla Site.
I want to update from 3.10 to 4.4.3.
I uninstalled almost everything, that could cause trouble.
Unfortunately the template we use is not available for Joomla 4 and the Company does not exist anymore (It's the JSN Metro Template).
The Problem now is: I do not have another template installed (i guess, years ago i deleted everything i thought i would never need again)
When I try to install the Protostar template again I always get an error message.
And when I go to Extensions -> Discover ("überprüfen" in german) i get the 1054 error message with this call stack.
Would be great, if anyone could help me.
Code: Select all
