One of my users suddenly got a number behind his username, which wasn't there before. The members cant change their usernames on their own, so that is not an option.

Any other explanation for this? (:

Hi there, can you please provide a screenshot along with your forum's URL? THanks.

Check to see if there is another account with the same username?

It should be noted, that the user: Christian2, didn't have any problems with registrering as Christian.
Even though there were an user named Christian before him.

Why is Christian2 in red?

This is not a normal behaviour. If your first Christian hasn't been deleted, no one should have been able to register to your forum with the same username.

I think this is due to the restauration of your old member Christian. If you delete this one, you'll be able to change the username of Christian2. The fact, I think (you can correct me if I'm wrong), is that the first Christian account was deleted, and then the new one signed up to your forum.

When we made the back up, the old one appeared again, and because it's not possible to have 2 members with the same username, the login of the new Christian became Christian2.

If the old Christian wasn't deleted, this is definitly not a normal behaviour and that might have cause a problem in your datas. Let us know about it
