I'm not sure what changed over the last few days, maybe it was the update to 3.3.1 or a plugin update, but suddenly all my posts are inaccessible. I have the default page permalink structure and every link which is domain.com/?p=XXX just bounces back to domain.com The odd thing is that the domain.com/?cat=XXX links all resolve properly. I tried changing the permalink settings to Post Name and all the post links become working again, but this is not a fix because all incoming links to posts then fail and all internal links to posts would need to be redone.
Has anyone else had this problem or know of a place to start fixing it?
