Politist Template - Class 'JString' not found
Which appears to be occuring on multiple pages with no special plugins/modules at all.....
It appears that - Failed to load resource: the server responded with a status of 404 () - a stylesheet is not loading templates/shaper_politist/css/legacy.css

Accepted AnswerHi Michael
I saw that you already touched index.php from template to remove legacy.css.
The problem of "Class 'JString' not found" was caused by old plugin plg_content_geshi !! It was plugin from very old Joomla version. Not used in J4.
I disabled it. Now is OK. Fixed.
