With the latest J4.2 , your admin module does not work anymore and might leads to a :
Class 'Joomla\Plugin\Behaviour\Taggable\Extension\Taggable' not found
On the front end.
And a 500 error while editing menus links into the backend.
Uninstalling the module brings back the native J! for menu editing, and does not impact anything.
Just to let you know, I had a 500 error, while editing a Yootheme builder.
It happens just once, couldn't catch the log, but it never happened before, and it was with the latest version of the module.
There's no reason this module was loaded here as it's indeed in the backoffice, but there's no Joomla admin or module, that might be a cache or something...
Sorry I can't say more at the moment, but in case taht makes you think about something...
