related posts / weaver theme conflict

I've discovered a conflict between

Related Post plugin

Related Post

and Weaver Xtreme theme

Weaver Xtreme

I'm using Weaver Xtreme Plus as well. I tested deactivating WX Plus to see if the problem is with the Plus plugin. The conflict is still present using only the free version of Weaver.

When Related Post plugin is activated pages which are created as Page Attributes -> Template -> Page With Posts will only display the first post, regardless of how many Posts per Page are specified in the Page With Posts tab for that page.

Turning off Related Post make the problem go away and the page will display the correct number of posts.

I've not noticed any other conflicts.
