Hi Community,
I just received an update on this issue from our engineering team and am pleased to report that we just finished releasing the change necessary to resolve this problem. As a result, you should now be able to successfully post any eBay UK listings that had failed to post due to these errors by posting or scheduling them again through your Auctiva account.
If you encounter any further difficulties when trying to post your items after this time, please contact our customer support team by mousing over the "Help" tab within your account and selecting the "File Support Case" option.
-Mike
