I have this plugin installed on my site and the front end is working fine. Users can submit and make use of all functions. The problem is with the back end. When I click on UPS in the post section I get:
Fatal error: Call to a member function set() on a non-object in /home/unreal/public_html/wp-includes/query.php on line 74
Any help to solve this problem would be great http://wordpress.org/plugins/user-submitted-posts/
I am running a few as my site has been active for about a year. The most recent plugins I have installed are Plugin Organizer, admin bar disabler, SimpleModal Login and memory viewer.
I have disabled plugin organizer and memory viewer.
The front end of the plugin works like a charm, even the setting page works perfectly. It’s only when I click on USP in the posts section that I get the error.
