I am trying to track down the cause of an odd behavior on our dev site that seems connected with CKeditor. We have installed and configured CKeditor 7.x-1.14, and everything is working fine except the Add Media feature.

When the Add Media icon is clicked, the appropriate dialog window opens and then two seconds later automatically closes itself. (See screenshot of the media dialog box.) The media dialog window NEVER stays open longer than two seconds, rendering the media features unusable.

The Drupal media module and inserting Drupal embedded media plugins are enabled. We have tried integrating (individually) CKfinder, IMCE, and CKeditor Media (dev) thinking it may be related to the file upload/browser but the problem persists. Not sure if this is related, but after the media dialog closes itself, the following is appended to the URL: no-cache=408802853467.6492 where the number is unique.

Has anyone run into this before? We need this feature up and running ASAP, and cannot find any help in the readme.txt, installation helps, CKeditor Drupal guides, and issues queues. We have used CKeditor in our other Drupal installations and have not had this problem.
