Hi Community,
Thanks for helping to bring this to our attention. I have looked into the errors that you have received and it appears that the root cause of the problem is that our Choose Item Specifics interface contains values for some of the attributes that are no longer considered valid by eBay. We are looking into what can be done to address the problem.
However, our system does have the current values for each attribute within the Custom Item Specifics interface so, if you have been encountering this problem, you should be able to work around it by entering your item specifics information in the Custom Item Specifics interface instead of the Choose Item Specifics interface.
If you have already saved data in the Choose Item Specifics interface, you will need to open it up and click the "Clear" button before you will be able to successfully post the listing with information in the Custom Item Specifics interface.
I hope this helps. If you need any further assistance with this matter, please feel free to contact our customer support team by mousing over the "Help" tab and selecting the "File Support Case" option.
