White page after authenticating in BE

Hi everyone,

I was working on my website (eefic.eu) but not with Metamodels. After installing a efg extension and finally deleting it with Composer, I can no more access to Backend. When authenticating, I got a blank page with this message : "
Fatal error: Class 'MultiColumnWizard\Event\GetOptionsEvent' not found in /home/eefic/sitev3b/composer/vendor/metamodels/core/src/MetaModels/DcGeneral/Events/Table/MetaModels/Subscriber.php on line 85"

Perhaps did MM update itself. I don't know. What can I do to have access again to my BE ?

Thanks.

* Backup!
* if you doesn´t work with MM, delete all MM folder/files, update and try again

... your cache is clear?

I don't know. Can I clear it when no access to BE ?

you can delete the cached files per FTP

Finally, I created a new vhost and reinstalled all then imported the db dump. Now it works. Thanks.
