JPagination
JPagination class name
JPagination is a Joomla 3 global class. Joomla 4 still has an alias. Joomla 5 needs the Behaviour – Backward Compatibility plugin. Native Joomla 6 does not load that alias — you get Class "JPagination" not found.
JPagination → Joomla\CMS\Pagination\Pagination
What you will see
- Class "JPagination" not found
- Class 'JPagination' not found
- Failed to open stream: JPagination
