Yay!! we have success!!
So I didn’t actually end up restoring to a previous backup, but you were totally right. The had revoked my status as admin, changed my password and create a new user (them) as admin.
I went into myPhpAdmin into the users table and deleted them as the admin and reset myself with the privilege.
Thanks for your help on the matter.
Thanks, I’ll try restoring to a previous backup and see what happens.
