I just merged forums, xenforo to MyBB 1.8 now i wanted to delete my new account but this error pops up?
Help please!
Thanks.
Is that account a super admin or are you trying to delete your own account (I mean deleting the account you're logged in with)? You can't do either. And the error is a bug, it shouldn't be shown:
