Ugly Fix... for anyone who may also have this issue here's my temp fix so that until Telerik fixes this your pages will still be indexed by site crawlers (assuming I'm not the only one having this issue).
I've added the following code to each of my custom .master pages.
protected void Page_Load(object sender, EventArgs e)
// ToDo temp fix to prevent noindex meta tag
foreach (Control hm1 in Page.Header.Controls)
if (hm1 is HtmlMeta && (((HtmlMeta)hm1).Name.ToLower() == "robots"))
I can't tell you how sick and angry it makes me to have to add hacks like this to a $2000 CMS!! Especially when this bug wasn't here in 4.0 or 4.1!
