We have received calls this week reporting issues with the administration area on WordPress when viewed within the IE9 web browser. The issue seems to be with the HTML text editor when adding or updating a blog post.

Reported issues are disappearing text when changing from HTML view to Visual View and tool bar problems on the HTML text editor.

This seems to be an issue with the editor itself which is the TinyMCE HTML editor.  TinyMCE have reported this as a known bug with IE9 that is now fixed and released so the latest versions of WordPress should have an updated editor which should fix the issue.

IE9 came out of beta in February (with an RC release) and the official complete product was released in March. I find the new IE9 browser much faster, cleaner and more reliable than its predecessor IE8 but it is only available for Windows Vista and Windows 7. If you can upgrade to IE9 then it’s a good idea. If you have upgraded to IE9 and you’re experiencing problems then let me assure you that a few kinks along the way is par for the course and no reason to go back to IE8.

For the time being it is advisable to simply use Firefox or Chrome a as an immediate fix. Firefox is my preferred and default web browser anyway.

A longer term solution is to upgrade WordPress to the most recent version and this seems to be working fine with the latest release of IE9 and other major browsers. To update your WordPress installation contact your system administrator or hosting support partner. If that’s Rake Mark, then don’t hesitate.
