Good Evening
I am trying to update from joomla 4.3.4 to later and the site is not working
It gives me these errors :
An error has occurred.
0 Class "Joomla\Plugin\System\Jooa11y\Extension\Jooa11y" not found
PHP Deprecated: Creation of dynamic property YOOtheme\Widgetkit\Widget\Widget::$path is deprecated in /home2/aliness/public_html/administrator/components/com_widgetkit/vendor/yootheme/framework/src/Plugin/Plugin.php on line 18

nikolasf Hi

As you can see the errors indicate the issue from 3rd party extensions on your site: Jooa11y plugin and Widgetkit from yootheme. They seems to be not compatible with the Joomla version and PHP version you updated.

You should contact the providers of these extensions to get updates.
