I have gotten this error message 87 times today. It happens about 60% of the time when I tries to see the details of any item. I happens anytime I try to go from the 2 to 3 page, or any page above 2, in order history 100% of the time in page 3 or greater from page 2 or greater. It also happens about 50% of the time when trying to go to the "Cart".
Yesterday I got it over 100 times.: "Bad Request Your browser sent a request that this server could not understand.
