Restoring a database dump of Opigno into another instance
In case you are restoring a database dump of your Opigno instance into another Opigno instance, you will need to regenerate the user IDs used for Moxtra so that your 2 Opigno instances aren't conflicting.
For this you will have to run this Drush command: drush sqlq "DELETE from key_value where collection='opigno_moxtra';"
