The Solution – Upgrade to WP 3.2.1
When I upgraded to WordPress 3.2, the Visual Editor for Posts and Pages stopped working. (Read below for a more detailed description and discussion).
The solution is to upgrade to WordPress 3.2.1 (Thank you WordPress Devs!)
Don’t forget to empty your cache before you check to see if this upgrade solves the problem.
Don’t Hack the Core to Solve This Problem
Sara Anderson suggested a solution to this problem (read about the problem below) on the WordPress Support Forum. She wrote:
Anyway, for us, our fix was to open up wp-admin/admin-footer.php and comment out line 36
This worked for me. Thankfully. I think it may be a bug so if anyone knows how to report it to the WordPress Devs, please write me. And many thanks to Sara.
The Problem – Visual Editor is not Working since Upgrading to WordPress 3.2
Ever since upgrading to WordPress 3.2, the Visual Editor does not work for Pages and Posts on one of my sites. Also the Admin Bar does not appear on these Admin pages. To try to fix the problem I have done everything mentioned on this thread:
The site with the trouble is using mySql 5.0.90 and PHP Version 5.2.12. However everything works fine on my local dev site with exactly the same plugins and theme where I am using MySql 5.5.11 and PHP Version 5.2.9
I have deactivated all plugins.
I have un-installed some mu-plugins.
I have reinstalled 3.2 automatically and manually.
I have checked all permissions for files in the root folder, wp-admin and wp-include folders and they are all correct.
I have changed the theme to TwentyTen and TwentyEleven.
I have emptied my cache each time after making a modification.
And I have tried numerous other solutions suggested.
The problem persists. Here is a screenshot of the Edit screen without the Visual Editor.
No Admin Bar Images
