IE9 breaks Kupu and TinyMCE

by Darrell Kingsley last modified Mar 13, 2014 02:21 PM
People using Kupu or Tiny on our sites can't get the main text to display, and can't click in the main text area when using IE9

This is a known bug with the editors, as they were developed before IE9 was available for testing, and obviously it would be too much to expect things that worked in older versions of the browser to work with the new version.

There are three solutions, other than replacing the editor (presumably new versions will appear which will work in IE9).

  1. Get the users to configure their browsers to run in compatibility mode
  2. Get the users to switch to Firefox, Chrome or Safari for editing.
  3. Add the following to the <head> tag of the main_template:
    <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" >

This *should* force the browser into IE7 compatible mode. It might be okay to make it IE8 compatible. This tag MUST go at the top of the page, above the <title> tag, or it won't work.

I'm about to add it to the bbwebsite for Plone 3 and 4 when SAL have tested it.
