Validation problem?

It would be a start to provide a link to your site first?

opps….. https://www.CreditAndCreditReports.com

It’s a linkfarm.

So what is being inserted between posts? Must be a tag of some sort – if you’re going to post things like tags you need to put backticks around them or they won’t show….

So is it <br /> or <li>, or something else?

Your problem stems from the fact that you’re trying to combine HTML and XHTML into the same document. You can’t have <font> tags in XHTML, while you can’t have /> in tags in HTML. Decide on which markup language you’re using, then revalidate.
