I've bought the plugin and want to use it with a wordpress

Hi

I've bought the plugin and want to use it with a wordpress theme builder, called headway themes. The automatically created pages of the classified plugin are shown when I use a theme which is not created with headway themebuilder. But when I activate the headway themebuilder and I click on the created pages, they always show just a blank page. See here -> wmpudev.latexchange.de - Do you have any idea whats the problem? I also already contacted the headway theme support, but thank you for any solutions.

kind regards

Patrik
