When trying to validate, I get the error "end tag for "script" omitted, but OMITTAG NO was specified"
I view the source code of the invalid page, and this is what I see:
I look at nrelate-popular.php and at the end ">" is indeed a ">". Eh? How can it be validated?
EDIT: the closing > for the source code should be the character entity (& g t ;). The file has the greater than symbol.
