I know you have multiple queries and guides about installing and using CKEditor and whatnot, but my CMS script that I had acquired a few months back had FCKEditor included, and to be honest, that editor is a little too simple; so, I downloaded CKEditor, and I have it uploaded to my server, and the /_samples/index.html file works. But the problem I have is that I don't know how to replace my original FCK with this new one. The script simply says:
include("FCKEditor/fckeditor.php") ;
