I have gone into the Configuration page for NeoRecruit, and I am getting an error at the top of the page... The error is as follows...

Warning: Invalid argument supplied for foreach() in /path/to/joomla/libraries/joomla/html/html/select.php on line 68

When I scroll down and look at the "Authors" field... there is no groups to select.

I am using Joomla 1.5 with the community builder extension if that makes any difference.
