ie-10-logoIf you have recently upgraded to Internet Explorer 10 or 11, you may have noticed functions not working correctly with SharePoint 2010 or MOSS 2007, or most recently, IE11 with SharePoint 2013. If your browser doesn’t respond to various actions or you see lots of different JavaScript or Silverlight errors, there are a few quick fixes.

First let’s identify if you are having compatibility issues:

  1. Did you upgrade IE?
  2. Is the SharePoint Ribbon not working properly?
  3. When you follow Ribbon buttons, are you receiving JavaScript or Silverlight Errors?
  4. Are SharePoint Galleries not loading content?
  5. Are Web Parts are not displaying properly?

If you answered yes to one or more of these questions, then you might have a compatibility issue. So let’s fix it!

Why is this happening?

ASP’s .NET 2.0 and .NET 4 has a bug in the browser definition files in unpatched versions. Specifically, these definitions are only applicable to a certain range of browser versions. Anything outside of these ranges for some browsers (like IE 10 or 11) are not supported and ASP.NET sees them as unknown browsers and defaults to a down-level definition, which has certain inconveniences, like how it doesn’t support features like JavaScript or Silverlight.

So how do you fix it? Here’s what we tell customers:
