Please follow steps:

1. Please open "cuteeditor_files\Dialogs\phpuploader\include_phpuploader.php"
2. search the following line:

   function PhpUploader()
 {
  $this->Name="AjaxUploaderFiles";
  $cd=dirname($this->GetWebPath(__FILE__));  
  $this->ResourceDirectory="$cd/resources";
  $this->ResourceHandler="$cd/ajaxuploaderresource.php";
  $this->UploadUrl="$cd/ajaxuploaderhandler.php";
3. if CuteEditor for joomla:
   update it to:
    function PhpUploader()
 {
  $this->Name="AjaxUploaderFiles";  
  $cd=dirname($this->GetWebPath(__FILE__));
  $cd = "/plugins/editors/cuteeditor_files/Dialogs/phpuploader";
  $this->ResourceDirectory="$cd/resources";
  $this->ResourceHandler="$cd/ajaxuploaderresource.php";
  $this->UploadUrl="$cd/ajaxuploaderhandler.php";
        if CuteEditor for PHP, how to get the value of variable "$cd"?
   a. save "cuteeditor_files\Dialogs\phpuploader\include_phpuploader.php" as "include_phpuploader(bak).php"
   b. edit "cuteeditor_files\Dialogs\phpuploader\include_phpuploader.php", remove all code of this file
   c. open cuteeditor, click button "insert image", you will find the upload button is replaced by one error message which looks like:
      Fatal error: Class 'PhpUploader' not found in /home/www/clients/client0/web15/web/plugins/editors/cuteeditor_files/Dialogs/upload.php on            line 99
   d. You can find php uploader will find file in "/home/www/clients/client0/web15/web/plugins/editors/cuteeditor_files/Dialogs/upload.php"
      the $cd value should be:
      $cd = "/home/www/clients/client0/web15/web/plugins/editors/cuteeditor_files/Dialogs/phpuploader";
