Such as:
Line 608, Column 84: there is no attribute “type”
… <div><SCRIPT type='text/javascript' language='JavaScript' …
The code provided by Alexa looks some what like this:
<SCRIPT type=’text/javascript’ language=’JavaScript’ src=’http://xslt.alexa.com/site_stats/js/t/b?url=nabtron.com’></SCRIPT>
To remove the validation errors you need to edit the widget code to have small letters only, like:
<script type=’text/javascript’ language=’JavaScript’ src=’http://xslt.alexa.com/site_stats/js/t/b?url=nabtron.com’></script>
It will remove the errors caused by the alexa page rank widget on your website upon validation from w3c html validator.
