The javascript below will fix that problem by redirecting the page to an URL without those two parameters. It is a simple javascript, just insert it into the HEAD section.

<script type="text/javascript">

// Dynamicweb CMS fix: Make sure that details view of news item is rendered correct

// Insert in Master page in HEAD section

// Will redirect to same URL but with any "M=News/M=NewsV2" removed

var loc = document.location+'';

var newLoc = loc.replace('&M=NewsV2', '').replace('&M=News', '');

if (loc!=newLoc) {

 document.location = newLoc;

}

</script>
