Two different users with the same nicknames...

Please look at the image below...

berk_20020 (uid=4824)
berk_20020 (uid=4825)





Also check the following board at www.eltcafe.net

Are you sure they don't have some hidden unicode characters in their username?

^ How does that help the issue here?


Unfortunately, the only sure method for checking for hidden unicode characters is to save the page and investigate it in a hex editor.

I'm sure there aren't any hidden unicode characters in their username...

If you're certain that's the case, the only possibility I can think of is a concurrency issue.
I might look into this one.

But anyway, for now, just delete the second account.
