Is not compatible with the Plugin Mootools Framework by Nils K. Windisch, Multibox by phatfusion and the NextGEN Smooth Gallery by Bruno Guimaraes. It's not compatible with the Theme sliding-door. Because the plugins and theme do not use the wp_enqueue_script() function. If you like to use the sliding-door theme. I fixed the problem. If you need the solution write me at BMo-Design.
