Odd Permalink Behaviour

Hi, Thanks for a great plugin.
After the latest update I’ve been experiencing some odd behaviour on my site.

When ever I have Mediapress active along with Buddypress and bbpress, my sites Pages all suddenly return 404 not found errors.

Even more strange, is that when I update the sites permalinks, the pages are actually visible for around 5 seconds before eventually returning 404 errors again.

I have tried everything I can think of to remedy this but sadly nothing has yet worked.

If I disable Buddypress, the sites pages become visible again.
Likewise, if I enable Buddypress and bbpress but disable Mediapress, the pages once again are visible.

But if I activate all three plugins together, all of my pages vanish, leaving behind a 404 error.

Any advice would be great.

Many thanks
