Every time I create new users, I get a host of MySql / php warnings. Any ideas?
Warning: Invalid argument supplied for foreach() in /wp-admin/includes/user.php on line 88
Warning: array_keys() expects parameter 1 to be array, null given in /wp-includes/user.php on line 1545
Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /wp-includes/user.php on line 1545
