ah right fair enough. I tried on 4 devices and no issues for me so thought it may be as simple as cache related.That's why I specified 3 difference machines, it's defo not a cache issue as the Mac was a brand new install of the latest version and my work laptop clears cache on browser exit
Plus as a guy on the other side of the world from me posted a pic of the same error in the Inn thread.
[EDIT]
It would seem Im not alone:
