I have a Page and a Post that I want to make changes to. When I click the Save button, the page refreshes and gives the message "Page draft updated." But the changes are not reflected in the edit window and, of course, not in the Preview page.
I can create new posts - they save just fine.
But changes made to existing posts don't stick, even though it tells me the changes have been saved.
This started happening last night, though I've been using WordPress for about a year now, and upgraded to 3.0.1 as soon as it came out.
