What kind of errors do you get? If you're using a lot of webcontrols that renders html by them self, they're maybe render legacy html. Please see http://msdn.microsoft.com/en-us/library/x3k2ssx2%28v=vs.100%29.aspx. You can change this behaviour by updating your browser files and give the w3c bot more capabilities.
Or even better; use webcontrols where you have full control over the html.
There are a lot of user controls, I will try your suggestion and report back :)
I am trying to validate a site, and the validation errors I get doesn’t match the site that went online last year.
It seems it validates a old cached version of the site, some of the errors is fixed and is not in the html markup anymore, so it shouldn’t still give an error.
Any suggestions to how to fix it? I can still validate with taking the html directly in, but this test should work for the link also.
I know this is maybe not a Episerver fault, but I can`t really find any other similare cases, so I will try here :)
