Fixed:

Followed the following instructions from http://www.wpmayor.com/code/easy-fix-for-wordpress-3-5-jquery-is-not-defined-error/

This is to solve the “jQuery not defined” error:

Insert the following code into wp-config.php:

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');

define('CONCATENATE_SCRIPTS', false);

Take care all!

I updated all themes, then changed to the twenty-eleven theme. This had no effect.

I renamed my /wp-content/plugins folder, then created a new one with 777 permissions. I moved only the tinymce-advanced tree into this new folder and logged into the admin panel again. Experience the same issue.
