Ebay's RSS Feeds are a mess right now. They are down, up, down, causing a lot of slow load issues etc.
I finally had to turn this plugin off today until Ebay gets their act together. So when I turn it off, like any shortcode device, the [..] feed text shows.
Fortunately, I put the feed in between div tags and was able to do a find/replace for the front part of the feed and force the div text to white so that it does not show up on my pages.
To the point, it would be really great if this plugin were to have a setting feature to "hide" all feeds, so that when issues like this occur, they will not muck up page displays. In other words, an on/off setting of some sort for feed displays?
