I do not understand what is happening exactly. I did notice that are still on WordPress 3.5.1 though; you said you tried 3.6? On the same site, and then downgraded, or how exactly?
I'd love to see a screencapture of what your steps are and what happens, exactly. Would you mind filming your screen for me? You can try to use this service to do so, for example (it's free):
Let me know; thanks!
