Unable to change nickname.

[Dev]

Hey everyone,

So I've been trying to change my nickname from 'Dev.' to 'Dev' via the UCP, but everytime I attempt to do so it gives the following error message:

But the problem here is that I searched all the pages in the members' list for nicknames starting from 'D', but I was unable to find any account using this nickname, So just wanna requesting a forum admin to either manually change my nick or tell me what's wrong.

"Dev" is a registered user with no posts who hasn't visited since 2010. I've deleted that user, go ahead and change your nick now.

Thanks a lot.
