my WP Installation on a Linux Mint Debian Edition has out of the Box without any installed plugins or themes a problem with a complete white and empty visual editor.
As described on
in step 2 I turned on script debugging in wp-config.php (respective in /etc/wordpress/config-localhost.php in Debian based systems):
Doing so, the visual editor works fine. Set the option to false or delete the entry in the file, the error comes back.
As descibed in step 3 I found in my error console:
Timestamp: 01.08.2013 08:24:48
Error: TypeError: this.getDoc(...) is undefined
Source File: http://192.168.32.8/wp-includes/js/tinymce/tiny_mce.js?ver=358-24486
Well - step 4 recommends to report the bug. So I do so...
