CKeditor cannot find ckeditor.js I am in the process of upgrading a Drupal install from 6 to 7. Drupal 6 uses the ckeditor module without any difficulties.

As I upgraded to Drupal 7 and the latest version of ckeditor, the module no longer works. 

Firebug gives me an error message: 

Failed to load resource: the server responded with a status of 404 (Not Found) http://mysite/ckeditor.js?mcqjp7


I'm not sure why ckeditor is looking in the site room for that file. 

It has no trouble finding the css file

&lt;style type="text/css" media="all"&gt;@import url("http://mysite/cms/sites/all/modules/ckeditor/ckeditor.css?mcqjp7");


So why can it find the CSS file but not the JS file?
You have to check the libraries for ckeditor in your drupal site.

sites/all/libraries/ckeditor


In D7 the CKEditor contain the libraries for editor. if you don't have then download the module and library from http://ckeditor.com/download
