i tried upgrading from dnn 7.1.2 to 7.3.4... after the upgrade the menus do not render. instead, dnn shows the menu items as text in tree format along the left hand side of the page with hyperlinks. the content of the page is shown strewn all over below the various menus.

I tried with 2 different skins but the same problem persists, with one menu being brand new and supported for 7.3. the menus do not render in ie11 compatibility mode or in chrome. so I suspect that the problem is dnn..

has anyone encountered this problem? any solutions?
