Nothing works when using the plugin

Hi,

I have struggled with this plugin whole day. I can design my custom skin for my products but when using it, it breaks my shop. How can reorder the products in an archive page? I have no controls to do that anymore. I cannot use functions to do custom stuff, because it doesn’t affect items in the loop. I cannot use plugins like WPClever favourites plugin. It doesn’t show up!
Please help me. I need to get my shop done for my client! ??
