I just upgraded to 3.3.1, and now I can only activate a certain number of plugins (6). If I try to install a 7th, the admin side goes blank. The public site is fine.
I can de-activate one plugin, and activate another, but that 7th I just can't.
Has anyone encountered anything like this?
The plugins I was playing with were nextgen, all in one seo, and WordPress SEO.
