There were errors in the code for updating the paid designs up until today. The new build I sent you seems to have fixed those. The older version probably already downloaded the new design, but didn't update the version number in the design window correctly.
Some links in the description are produced by the code contained in the designs. Old design don't know about eBay's new http requirements.
So, unless you were listing or revising your listings with version 2.5 of the Pro:Urban design (which we updated to meet eBay's new requirements), your listings still contain http images.
GarageSale doesn't auto-revise you listings when a new version of the used design appears. You might have made changes to a listing on the eBay website, that GarageSale doesn't know about. These changes would be lost of we would overwrite your listings description automatically.
Hence, you have to follow our instructions here, to make the http images go away:
