I am having this exact same problem. If I rename my plugins folder, then I can get the page to load. Then I’m able to access screen options and change the number of posts per page. After that, I rename the plugins folder back and violoa, I’m able to see my lists of posts again.
The trouble with this method is that it only helps me, not my other users (unless I had everyone go in and do this at the same time.) What I’m now looking for is a way to decrease the default number of posts per page.
I am assuming that there must be something going on with a particular post that is causing it to return a huge result set causing the memory error. But I’m just a novice so I may have no clue what I’m talking about. (very likely actually.)
