I am using Nice Menu's on my Omega Subtheme and I got them working just fine, but I am seeing a random error, can anyone tell me if my PHP is correct? Thanks!
Warning: call_user_func_array() expects parameter 1 to be a valid callback, no array or string given in theme_get_registry() (line 276 of /home/content/02/10213802/html/includes/theme.inc).
For some reason Drupal.org is failing on my post with the PHP code, I will link to the .txt file which contains a copy of my PHP.
Side Note: I made this change in region--menu.tpl.php
