Another problem guys , it show the message below when i want to see my profile ,

"This user has not registered and therefore does not have a profile to view."

when I click on your user name - then cilck on [ View Profile ] I receive

vBulletin Message
This user has not registered and therefore does not have a profile to view.

I think you have a error with your user name

I think the reason you are having these problems is because your username contains a backward slash, which vBulletin is obviously failing to recognize. You will need to change your username to something without a backslash; however this is not possible as your username can only be changed once.

Therefore, an administrator will need to change it.

To prevent complications, it is best not to use system confusing symbols in a username like slashes, periods and other strange symbols.

Yeah, I think the Username Change script is a little hacky, and directly changes the database entry in the database, which is why it didn't catch the \ symbol.
