The eBay website seems to be partially inactive. I can’t add any items to the cart, nor add them to the watch list or enlarge photos of the item. This is the case with every item and every seller.

You're the only one so far with a report like this. If it were eBay's fault, the forum would be full of it.Are you getting an error message?Tried clearing the cache & deleting cookies? Tried a different browser?
