GP Premium conflicts with MemberMouse

Hi Tom, I'd created my sister's site using GP and she then added the MemberMouse.com plugin and BBPress to set up a membership area on it.

Unfortunately the GP Premium plugin was creating a conflict which meant that none of her navigation for the site worked and it would only display the sales page and nothing else. We know it was the plugin as we deactivated everything and then turned on each plugin one by one.

I thought I'd found the conflicting Add On in the plugin and disabled it - Spacing - but then the problem happened again a few hours later and my sister lost patience and installed a different theme which is working fine.

I just thought I'd let you know as I really love using your theme and have two more sites I need to set up with MemberMouse.com - I'd really like to use GP if you can figure out what's causing the issue? Bit hard maybe as I don't have a live site with the problem to direct you to.

Sarah :)
