I have installed the CKEditor module for Drupal 7 version 1.14. This version of the module comes with CKEditor already integrated with the module, so I am not sure how to find out exactly which version of the CKEditor this module comes with by default. I need to know this because when adding plugins from the CKEditor website only certain versions of the plugin are compatible with certain versions of the CKEditor. So how can I find this out? I have looked through the different module and JS files but I cannot find this information anywhere.
You can go to Ckeditor module in your contrib module list and open the readme.txt file. At the section "Requirement" you can see the compatible version of ckeditor library that you can download. the section look like this :
Requirements ------------ - Drupal 7.x, - PHP 5.2 or greater, - CKEditor 3.4 or greater. You will need to download CKEditor from the official download site: http://ckeditor.com/download. It is recommended to always use the latest CKEditor version available.
