New User Was Able to Register with Admin's Username

[Muzza]

I have a problem!

I just noticed that a new user was able to register with my username (the admin).

I changed the username of the new user and now in the "latest post" column, any latest posts made by me are now listed with the revised name of the new user?

Can you follow this??

Thanks for the link.

That link doesn't really explain, however, why I have posts (which I made) that have the new person's revised username attached to them in the "latest post" column?!

If I delete the new user will that temporarily fix the problem?

Have you tried Update Counters > Rebuild Forum Information?

If you click on the link in the Last Post, do the actually last post have your name of the other username?
