Conflict posts with wp-catalogue plugin

Hi,

There is a conflict between my template and the plugin wp-cataloge, the problem is that if I have activaod the plugin only shows me 1 post on the website and I can not change it in settings –>lecture. I can change it only if is it disabled the plugin.

Any idea where could be the conflict between the catalog and the template?

Thank you very much, otherwise great plugin.

Kind regards.
