Membership 2 theme conflict

Hi, when I activate content protection on our website the header and footer menus are not loaded. Also there is a video running, which keeps loading.

When I disable the plugin, it all works fine again. I already deactivated page transitions for my theme.

Could you help me out, since the membership plugin is the reason I got a membership with WPMU Dev in the first place.

Kind regards,

Joost
