Uploaded files with CKFinder and QuickUpload

This has been fixed in FCKeditor 2.5 (which should be released soon), all paths are easily configurable.
In fact, you don't have to wait and can test it even today by downloading the "nightly build".

Paths in CKFinder can be adjusted via config file, so you can remove "s" at the end of folder names.

Hi again,

To use Firebug, first you have to enable it (Tools -> Firebug -> Open Firebug). At the bottom of your screen you should see a new window.
Select Console tab to trace all AJAX calls. Also, if any javascript error occurs, you will see red warning in the right bottom corner (click it for more details).
I've tried to reproduce that error, and it seems to me that either you had invalid resource types defined in the following line:

$config['DefaultResourceTypes'] = 'Files,Images,Flash';

(perhaps you forgot to remove "s" also here if you changed resource name as well)
or probably you forgot to adjust AccessControl entries.

The only place where you had to change directory name were directory and url, like in this example:

$config['ResourceType'][] = Array(
   'name' => 'Images',
   'url' => $baseUrl . 'image',
   'directory' => $baseDir . 'image',
   'maxSize' => 1024,
   'allowedExtensions' => 'jpg,gif,jpeg,png',
   'deniedExtensions' => '');

Again thanks for the info, it helped us to understand that we need to work more intensively on displaying appropiate errors to the user.
