KCFinder show blank window when upload the image with ckeditor

Question

This is working fine on local system but not working on server.

KCFInder configuration detail

kcfinder/conf/config.php

$_CONFIG = array(

// GENERAL SETTINGS

'disabled' => false,
'uploadURL' => "http://mylocal/uploads/ckeditorImages",
'uploadDir' => "/var/www/html/mylocal/public/uploads/ckeditorImages",
'theme' => "default",

Answer 1

the uploadDir seems to be incorrect.
/var/www/html/mylocal/public/uploads/ckeditorImages shouldn't work on your server.

I think you should look over to this post for more informations or search on KCFinder project.
