After upgrading some extensions in Joomla 4 website I got an error
Class 'JError' not found
What to do ?
I think, it hapenned with template Purity iii, because only my one page Home page is assigned to this template. I like this template because of many positions.
All other files are with Casopeia and they works. Purity iii was updated. I see "2 changes found"
Pls give me a solution to solve this problem.
On my homepage I see this error, but in preview of home page I see my homepage with all positions,
here it is
