Hi, today i buy "JA Megafilter Component 2.0.3" and install on clean J3.10.12.
Unfortunetly when i try to go to admin panel i have an error

An error has occurred.
0 Class 'Joomla\CMS\HTML\Helpers\Sidebar' not found

An error has occurred.
0 Class 'Joomla\CMS\Form\Field\ListField' not found

Can u help me in this issue?

It seems to be issue with Joomla 3 when we update JA Megafilter for Joomla 5.
