I'm new to the idea of RSS feeds and I've activated the pluggin in word press. I've been trying to add a RSS feed from an eBay store and I get this message with errors. "The RSS feed you have entered does not exist. (21800)"
I've tested the code just in the address bar of my web browser and it works. I've even tested it on a free rss feed on some other site and it works. Let me know what I'm missing or doing wrong.
