The menu opens but nothing happens when you click on a menu item
See if this is enabled DivX Plus Web Player HTML5 <video> in your browser, if so disable it like this
Open IE > Tools > Manage Add-ons > Select “DivX Plus Web Player HTML5 <video>” Add-on > Click Disable > Restart IE.
Otherwise try resetting your IE settings in the advanced tab.
If the above not working with you, you can try by Open IE Dev tools (F12), change browser mode to anything , page will refresh, now go back and change it to IE9 and change Document mode to IE8 Standards.
