Hi Suzanne,
The common factor on both listings is the page within page embedding that was the cause of code drop-out (lost code including background) when you use the Revise listing editor at eBay. When I re-did that code for the problem background loss, I noted the <html>, <head>, and <body> codes were apparently a problem for eBay, as those codes were being removed during Revise. I've seen other Auctiva members have the same code problem, but not a listing status problem.
Have you had any checkouts on listings where we updated the code to fix the background with that Style snippet I created? If those are working correctly, it's at least circumstantial evidence that the Template is involved.
