Yes, that fixed something. I got a new message

The document located at <http://markjmartin.com/feed/&gt; was successfully checked as well-formed XML. This means that we were not able to determine the exact document type, but that the document passed the XML well-formedness syntax check. If you wish to wish to perform formal validation of the document, you can use the “Document Type:” option of the validator. The parser implementations we used for this check are based on OpenSP (SGML/XML) and libxml2 (XML).

but a warning:

Warning No DOCTYPE found! Checking XML syntax only.

The DOCTYPE Declaration was not recognized or is missing. This probably means that the Formal Public Identifier contains a spelling error, or that the Declaration is not using correct syntax, or that your XML document is not using a DOCTYPE Declaration.

Validation of the document has been skipped, and a simple check of the well-formedness of the XML syntax has been performed instead.

Learn how to add a doctype to your document from our FAQ, or use the validator’s option to validate your XML document against a specific Document Type

Also, would the javascript be in the social media share buttons? What problems does this cause?

Thanks!
