SOLVED: “Open with explorer” disabled in IE11

I found that this button was disabled because of this line in my Master Page – I am using Bootstrap theme from Codeplex and that comes with its own master page.
What I had to do was change this line in the header from:

And now, the button is enabled and working!
I have an issue with Internet Explorer 11 and SharePoint 2013. The option “Open with explorer” is disabled, it works in IE10 but not IE11:

– checked that the local service WebClient was started

And obviously it is working in Internet Explorer 10. Maybe there is a new hotfix or something that needs to be installed, have googled this but not found any proper solution yet.

Hi Jay
I can't really remember what I did, this was more than a year ago (the date in this blog post is not correct, it was imported from my other blog). But I think I had to "emulate" the browser version by changing from IE11 to IE10 in this line:

meta http-equiv="X-UA-Compatible" content="IE=10"

in the HEAD section.
Hope this helps,
