This is the error that appears when navigating to a page with a Minitek Wall module on a Joomla 4 site.
File: /home/xxxxxxxx/public_html/components/com_minitekwall/libraries/source.php
Line: 24
Error: Class 'MSourcecontentSource' not found
Debug notice: Attempted to load class "MSourcecontentSource" from the global namespace.
Did you forget a "use" statement?
This error appeared only after updating site to Joomla 4 and updating the component and module to the Joomla 4 version. If I disable the module in the extension manager the error goes away, but of course then all content from the wall also does not appear.
