My RSS Feed will not validate via Feedburner, Chrome or Safari but does display via Firefox.
When I attempt to view my RSS feed, "http://joncobler.com/feed" I get varying results. Safari won't display, Chrome says that there is no style information yet Firefox displays it fine. When I attempt to burn the feed to feed burner it won't validate with error (The URL does not appear to reference a valid XML file. We encountered the following problem: Error on line 1: The entity name must immediately follow the '&' in the entity reference.) When I check it via feedvalidator.org, it says that it's good to go.
The feed worked fine previously, I believe the update to 3.0 changed things, but I'm not sure.
I host at 1and1. The wordpress files are in a subdirectory /domain/blog/ ... Any help appreciated.
