I have updated my site from Joomla 3.10.11 to Joomla 4.2.9 and using JA Alpha template. Everything is working except Contacts - List Contacts in a Category.
I get Error 0
Class 'JEventDispatcher' not found

Can you help with this issue? Thanks!

Hi @robert-vining

I have checked and found that the issue originated from the file ‎/templates/ja_alpha/html/layouts/joomla/content/category_default.php, which was not present in the JA Alpha template. Did you override this file?

Thank you, this is the problem!!! I did not see this in /layouts folder. This layout override was created during original J3 site build in 2021.

I removed the layout override and now the error is gone. Problem solved. Now to create new layout override to customize my layout.

Thanks again!
