I think the installation instructions for FCK Editor are a bit unclear. Here’s how I installed it:
1- Download the zip file and extract all files to your harddrive (I find the desktop a good place);
2- You’ll now have a folder called "FCKEditor_2.6b";
3- Look inside this folder to find two folders: "assets" and "install";
4- Copy the whole "install" folder to your site’s root folder (if you have the original MODx install folder still there, you need to temporarily rename that);
5- Now open the "assets" folder inside the "FCKEditor_2.6b" folder;
6- You’ll find a "plugins" folder in there. Open it;
7- There’s a "fckeditor26b" folder inside;
8- Copy this "fckeditor26b" folder and paste it in the "assets>plugins" folder of your MODx site (notice there is already a "tinymce212" folder in there);
9- Now run the installer (
http://www.yoursite.com/install/).
Done, you should now be able to select FCK Editor from the list of editors.
I hope this helps someone... It took me a while to figure it out
