wp-classifieds error

I am trying to get the wp-classifieds working on my site but as soon as I activate the plugin I get the following error:

Warning: Invalid argument supplied for foreach() in C:\Domains\nomoreboss.co.za\wwwroot\wordpress\wp-includes\functions.php on line 1052

I have the plugin working on my local computer and it works fine.

I would really like to use this.
