[Theme: EvoLve] Is Evolve Pro compatible with Buddypress?

Based on info above, there are two issues with the site:
1. Evolve theme integration with BuddyPress and
2. Integration of s2member plugin with BP/WP site.

For #1, it’s a matter of imposing the HTML structure of Evolve theme onto the BP template files which were transferred to your WP theme folder during the BP template pack compatibility process. Looks like you missed some opening and closing divs in the layout of your BP pages.

If you require further assistance with BP template pack plugin, please post at BP forums

For #2, best way to test whether the plugin s2member is working in your site is by changing to bp-default theme. If it works using that theme, then there’s probably a conflict with Evolve theme. You can either bring the issue to theme dev forums or to s2member plugin forums.
