New installation of WP 3.0.1, all is fine except that as soon as I try to activate a fourth plugin, I can no longer edit posts or pages, nor add new posts or pages.
All I get is the title box (if I'm lucky) and nothing else on the page loads.
I've tried deactivating plugins and reactivating them in every order combination possible, with the same results. Regardless of what order I activate them in, as soon as I activate the fourth plugin, I have trouble with Posts and pages. It goes back to normal if I deactivate one plugin.
This is highly annoying since I need to activate several more plugins than just three.
Has anyone else run into this?
