Many older Blogger templates include a meta tag that forces all versions of Internet Explorer to behave like Internet Explorer 7. Because Disqus supports Internet Explorer 8 and higher, this will break functionality and users won't be able to comment even with the latest version of Internet Explorer. Below are instructions on how to fix this.
- Go to your blog's Template section and then click the "Edit template" button
- Locate the following line within the <head>...</head> tags:
<meta content='IE=EmulateIE7' http-equiv='X-UA-Compatible '/>
- Replace it with this line:
<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7; IE=EDGE; chrome=1" />
- Click Save Template to apply your changes.
