@Ramesh8248May 23.2015 — #I think its happening because IE isn't supporting language of the website. Try adding some text in English and check if it is working or not in IE.
@Kevin2May 23.2015 — #Just for fun I opened up the OP's site with my old, decrepit XP-SP3/IE8 machine. This is about the most stock, bare-bones installation of that combination you will ever find. No frills, no extra fonts, no extra anything. Here's a partial screenshot:
@Kevin2Jun 12.2015 — #It's all really a matter of your target audience. One site I manage is extremely local. 10 mile (16 km) radius, although some of the content is intended for a wider audience. IE-anything accounts for about the same US figures that nap0leon gets. And if the junk hits from Russian, Ukrainian, and Chinese spam/probe servers are removed it's less than that. More like 8% or less of real live human visitors. In fact, that site is really close to having the majority of human users visiting with mobile devices and browsers. It's in the 45% range now.
Recently, while educating myself about Windows 10, I read that although "Edge" will be the new default MS browser, IE11 will be shipped with certain versions of 10. Why? The same reason IE6 is still used in some businesses. IE11 has a "backwards compatibility" mode to allow those old and tottering business apps to run and Edge does not.
