# WP 4.1, Visual Editor missing, Query strings problem

 * Hi I have updated WP to 4.1 and the Visual Editor is missing.
 * I have narrowed the problem to getting the tinymce JavaScript files e.g.
    …/wp-
   includes/js/tinymce/plugins/wpeditimage/plugin.js?wp-mce-4107-20141130
 * I have checked that the files exist but I get a 400/403 error IF AND ONLY if 
   the query string is appended to the end, in my case this is `?wp-mce-4107-20141130`.
 * In other words when I remove the query string the file is found see [example here](http://goo.gl/agqCn3),
   However with it I get a [error here](http://goo.gl/3yuYZS).
 * Other things I have tried.
    - The Master list
    - Revert Theme to Twenty Fourteen/Twelve etc.
    - Disable plugin one by one AND rename plugins directory
    - Multiple browsers
    - Manual Upgrade – Deleting and re-installing all core files wp-admin, wp-includes
      and all plugins by hand
    - Adding `define('SCRIPT_DEBUG', true);` to wp-config, and clearing caches
    - Searching Forums here
    - Running through the [Diagnosing JS Errors page](http://codex.wordpress.org/Using_Your_Browser_to_Diagnose_JavaScript_Errors)
 * This is where I found the specific problem
    Any help greatly appreciated

 * Your host may be running a firewall which is configured to block query strings
   on certain files, like mod_security.
 * I recommend checking with them.

 * You’ll probably need to contact your host too. Server-side firewalls usually 
   cannot be modified by hosting customers.
