I post auctions regularly, and for some reason today whenever I put an item into the AH to post, the "post auction" option is greyed out, no matter what the item is (random non-bound gear). I am well below the limit for the number of allowed auctions i'm allowed to have posted at once. This is what appears, everything's normal except the post button is greyed out and there seems to be a slight distortion in the thumbnail image of the item being auctioned. (Note that the "this item cannot be auctioned" error in my chat box is from when i tried to put in a bound item a few tries earlier to see if that made any difference, not the current item)
