I have been having the same problem. I am unable to post new blog entries because when I go to save a post I get a white out. Everything works fine until I click on the “save and continue editing” or “save” buttons. Interestingly, the title appears, but not the text or images. Whats also strange is that even with the white out, the post is still saved in my admin as a draft. When I tried to work on the draft this morning, there was a string of about 100 urls for prescription medication at the end of the saved draft.
