BuddyPress.org

I tested it with a new installation of buddypress without problems.

But if try it with my working installation copying all in /wp-content/plugins/ it gives me a blank page. So I get the error before I’m able to activate it.

I deactivate all plugins. but still the same issue.

I don’t want to reinstall the hole wpmu bbpress and buddypress site.

Also all ather plugins I use are working without problem.

The mu and buddypress site is working correctly.

Is there a way to find the error?

Or do i need to reinstal the hole working installation and hope that it will work after?
