Any ideas guys?

I just got this when I went to add a new user in the Admin CP :
Warning: array_merge() [function.array-merge]: Argument #1 is not an array in [path]/admincp/user.php(545) : eval()'d code on line 11

Any ideas about this one?
Thanks.

Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

I will try that out, thanks Lynne, I knew you'd be ready to help.

have you got one of the log in to a users account modifications installed?
