If you are using eBay Partner ads on your site you may have had the same problem I had: When I made the transition from "http" sites to the more secure "https" sites, my visual eBay ads disappeared.

It took me awhile back and forth with eBay Partner Help but I found out what is going on and a workaround. Here's the scoop:

Their visual ads are blocked by the "https" secure sites and will not show unless you know exactly how to bypass the security, which is different for every browser. That's no good to me because I don't want my potential customers not seeing my ads - even if they knew how to unblock the ads they wouldn't know to do it because they can't see that there is a problem. eBay help told me they are working to resolve this issue.

In the meantime, if you still want to use eBay Partner ads, you can effectively use their "Link Generator" with is text-only and no graphics. I'm now using them on several of my sites.

Hope this helps anyone who is having this problem.
