Hello, can you please help me to update my PHP version from 7.4 to 8.2?
There is an problem samewise as mentioned in this post: https://www.joomlart.com/forums/d/44586-category-list-error/3
For some reason, I get the following error message when clicking on an article category:
"0 Attempt to modify property "params" on null"
Joomla version 4.3.1
PHP version 7.4 -> no problem with the category view.
PHP version 8.x and higher gives the error.
I think it is a problem in de category view / settings.
You solved it in the post: https://www.joomlart.com/forums/d/39888-t4-warning-when-clicking-article-categories
I can sent you a username, and password for an admin account if needed.
Kind regards
