 * I have done everything that is supposed to be done in this article
    [http://wordpress.org/support/topic/troubleshooting-wordpress-35-master-list?replies=4](http://wordpress.org/support/topic/troubleshooting-wordpress-35-master-list?replies=4)
 * and after checking stuff that this article ask ;
    [http://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors](http://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors)
 * here’s the error that I got from Chrome and Firefox browser
 * Uncaught TypeError: Cannot call method ‘add’ of undefined post-new.php:1068
    
   Uncaught TypeError: Cannot read property ‘canvas’ of undefined load-scripts.php:
   441
 * SCRIPT_DEBUG did not fix the error. I can only use wp 3.4.2 , higher than that
   visual editor won’t show

 * Did you manually update WP to a lower version after installing 3.5 (or a higher
   version than 3.4.2)? That itself can pose a myriad of issues…

 * I asked my vps support team to check on this error
    he too have the same problem
   on his browser and this was his comment on mod pagespeed
 * > The Apache module mod_pagespeed is actually not installed:
   > =============
   >  -bash-4.1# httpd -M|grep speed Syntax OK -bash-4.1# grep -r 
   > pagespeed /usr/local/apache/conf -bash-4.1# grep -r pagespeed /usr/lib/php.
   > ini -bash-4.1# =============
   > And moving your .htaccess file, which contains the configuration for pagespeed,
   > to .htaccess.bk still produces the same errors in javascript console. This 
   > appears to be a coding issue and will need to be addressed by a developer.
 * i have run out of ways to battle this . from the way this is going it really

 * in case someone stumble on this thread and wondered how it end up
 * the first support guy that took my ticket keep insist that it was wp problem,
   but then Another technician on my host came in and take over the case found it
   out
 * the caused of visual editor not showing is due to reverse proxy by nginx.
    , 
   what he did was reinstall nginx and remove any additions that could’ve been preventing
   JavaScript.
 * to my delight wordpress is charmingly working now 🙂 hope it helps you guys out
   there
