Since a few days ago your documentation site (https://ej2.syncfusion.com/aspnetmvc/documentation) doesn't work in Internet Explorer 11 and SeaMonkey 2.49.3.
In IE clicking on a control name (or + sign) opens a submenu, but none of the links to the pages work. For example, Click on 'Calendar' opens a list of pages, but click on Globalization doesn't work.
In SM even submenu doesn't open.
It works in Edge.
