I had this issue when JoomDev developed the Framework also. And they fixed it for me by changing some of the code manually in menu.php. It's still on their GitHub page also. However the fix no longer seems to work in Joomla 4, it only worked in Joomla 3.

Here is the error messages.

The error occurs only on pages where YooTheme Widgetkit or Zoo exist. Pages that don't contain those extensions work no problem. I'd really like to move back to Astroid Framework but my website is mostly Widgetkit & Zoo based and need it working before I can.
