Dear friends,
Yesterday I had to restore my MT OS backup so I restored my MT OS backup and my usermanager backup but after restoring the usermanager backup I have lost everything which is related with my usermanager. I don’t know what is wrong?! but no customer and no user is there, and can login with my customer owner account cause that AC is gone. I was just DOOMED for that cause I have so many user related with usermanager, don’t know what to do now?! I have to make all the user and customer account again, what else can I do? I don’t have all the user info too. Too sad 
BTW the backup are been saved just a day before yesterday.
