I followed the steps mentioned here:
How to remove a package from Laravel using composer?
including the step: Remove Service Provider from "app/config/app.php" (reference in "providers" array)
However, since I got an error:
In ProviderRepository.php line 208:
Class 'Ckeditor\CkeditorServiceProvider' not found
Script @php artisan package:discover handling the post-autoload-dump event returned with error code 1
The app is down and I cannot do any operation in terminal. How to get rid of the reference to this class?
