If you look on the right-hand side of the page, under publishing, I am getting the same error for about 50% of my site. I have no idea what the issue is. If I click the “fix error” link, it wants me to enter an ISBN, UPC, etc. Sports Cards do not have this and I have no idea how to fix this or what to do. It isn’t solely happening to Sportscards, it’s happening to other items too. Can anyone help point me in the right direction with this?
I have also received several emails telling me my theme license is “illegal and needs to be changed”, however, I haven’t dealt with that as it seemed to be a scam. For reference, I used Dawn as the theme. I’m not sure if one issue has anything to do with the other.
