KB10072: Content Editor does not work when using IE 9

Content Editor is not supported under IE 9 out-of-the-box, please use workaround.

SYMPTOMS

Content Editor of AxCMS doesn’t work correctly using Internet Explorer 9. Some of the functions cannot be used anymore and there are problems adding texts and other elements to a page.

SOLUTION

To workaround these display issues, it is possible to make configuration changes in IIS so that special instructions are sent along with the HTTP response, telling IE9 browsers to display the data the same way IE8 would.

Configuring the EmulateIE8 HTTP Header in IIS7 (via the user interface)

  1. Open Internet Information Services (IIS) Manager
  2. Select the Server from the connections pane
  3. Right-click on “HTTP Response Headers” from the center task pane, and choose “Open Feature”
  4. Select “Add” from the Actions Pane
  5. Add a custom header with the Name “X-UA-Compatible” and the Value “IE=EmulateIE8”

This will then automatically cue Internet Explorer 9 to use the desired Compatibility settings so that your web application continues to generate web pages which are correctly displayed even in the latest version of Internet Explorer.
