Hi all, i haven't had the need to add a user via the admincp until today, when i go to USERS>ADD NEW USER i get the user profile window as you should but i get this at the top of the window:
Warning: array_merge() [function.array-merge]: Argument #1 is not an array in [path]/admincp/user.php(545) : eval()'d code on line 11
