I am having the same problem with version 3.3.2. Still looking for a solution.
Brand new installation with standard plugins and get the same grey screen right out of the box. Happens when trying to post an image and when trying to preview or install a theme. Other installations at same time and same browser no problem. As there a many posts with same problem that are unresolved I assume that above solutions were merely coincidental. Looking for a real solution by reviving this post.
I am getting quite frustrated with this as I have tried several methods found by internet search including one that inserts new password with code. I am afraid I am going to be forced to start over. Before I do that is there a way to repair the wordpress installation? Any other suggestions?
Thanks in advance.
