I'm in the middle of building my website which i'm trying to make standards compliant which i have check on w3 validator and it checks out as valid xhtml transitional 1.0, but the only problem is i have to have a php include for my news to be dynamically diplayed onto the website so have to put it to index.php and obviously the parser is throwing up errors everywhere because of it...
I think the validator doesn't like something in your include. Check to make sure the code in your include is valid as well. Plus the validator hates some of the url's included in these types of files also.
