IE7 compatibility mode does not work in DNN 5.6
How do i get this meta-tag to work, so that IE9 runs as browser mode IE7 compatibility and document mode IE7?
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
There is an MSDN article that is having full detail about this topic. Also there is another blog entry here that says, "It seems like the X-UA-Compatible tag has to be the first tag in the section."
