impossible to activate ckfinder

Hi,
this message shows in our Wordpress plugin when user forget change ckfinder_config.php file (shipped with plugin) to config.php file (override config.php file shipped wiht CKFinder). This message can be a little confusing. We will change it in future versions.

Have you activate plugin and than install CKFinder as described in readme file ?
You have you error when try activate CKEditor for Wordpress plugin or set it to use CKFinder ?
Try do it in this way:
- install and activate CKEditor for Wordpress plugin
- install CKFinder as described in readme file

Hope this helps you

What version of plugin , Wordpress and CKFinder do you use ?
Can you attach screenshots shows your upload plugin settings , directory where you have ckeditor-for-wordpress plugin and direcory with ckfinder ?
Please check chmod of you config.php file maybe script can't read it ?

I have tested this configuration today and everything works fine.
I have installed and activated ckeditor-for-wordpress 3.6.2 than download & extract CKFinder 2.1 into pathToWordpress/wp-content/plugins/ckeditor-for-wordpress/ckfinder directory . After this in CKEditor's plugin setting I set "File browser" option to "CKFinder" in "Upload options" tab.

"invalid config.php detected" error is thrown when config.php in the ckfinder folder does not contain string "wp-config.php". It means that the operation of renaming ckfinder_config.php into config.php was not successfull or that maybe you have renamed that file in a different WordPress installation.

The correct config.php in the ckfinder fiolder should contain around line 18-19:

require_once(dirname(__FILE__). '/../../../../wp-config.php');
require_once(dirname(__FILE__). '/../ckeditor_class.php');
