Trying to run an upgrade for Maximizer 11.5. Part of this upgrade includes the ability to use Maximizer Web Access. The current version does not play well with IE9 showing only a black white box instead of the full interface. I tried switching the browser to IE8 mode and everything started working again. How can I force the browser to always do this for everyone? No problem!
Open up IIS and add a custom HTTP header. Notice here that the name is “X-USA-Compatible” and I have set the value to “IE=EmulateIE8”. You can also force earlier versions of IE. Close your browser, reopen the site and it should magically work again.
