Membership Pro 2 not working properly

Hi,

I have installed Membership Pro 2 and followed all steps in the documentation. However, as soon as I protect the page my members can't access the pages and buddypress after they login.

I've tried it with existing members and by adding new members but nothing seems to help.

Searching the support forums didn't solve this problem.

Any idea what the problem might be?

Grtz,

Sander
