I've just noticed a problem today (Hope this hasn't already been covered).
The site is acting very weird whenever I edit a post. The edit works fine, but then when I try to leave the page, I get a "This method is only available by POST Hit the Back Button" error message. (At least when I click one of the "top" links).
I hit the back button and it shows my original post, without the edit. When I click on "edit", the new edit is still there. Close edit, it shows in the post, but won't let me leave the page (or at least, use the "top" link - I will need to play around with it some more).
If I close the page, and get back to ECF and re-visit it, the edit is there.
On a Desktop, running Firefox.
ETA: Testing 1,2,3
