I arrived just a few minutes ago and it all works perfectly. Try logging out, leaving the website and delete all coockies and close the browser. Then return. I think whatever it was has been fixed now.
@GOG! Please could you put up a warning news post and tritter, if you have that, whenever you update the website in a way that may cause hiccups. You can lock it straight away and remove it, or have it remove itself automatically, an hour after the website should work again.
