This start randomly. When I try to create a post within BuddyPress/Group or when trying to post with other plugins WP directs me to wp-login.php even though I am already logged in. Everything was working finds so this is something that started out of the blue.
I have disable all plugins that could be causing the problem but the problem persists. My uneducated theory is that something goes coo-coo when WP sends a request to the db. Throughout all of this I am logged in as an admin.
My main plugins are BuddyPress and Courseware.
