Error:  This error normally happens when the information you are sending to eBay from Suredone doesn't match up with the information on your existing listing on eBay. If you make changes to your variation listing in Suredone ie. changing any of the variation data for any variation fields or trying to add a new variation field to an existing listing,this will cause the data on Suredone to not match what is in eBay.

Solution:  You have to disable the item and then re-list it under a new eBayID to account for the new data that you were trying to send.
