I have problems with a site regarding IMCE. Users can't have access to the file tree. They have all the necessary permissions. IMCE is fired by CKEditor. I have attached a screen capture. Any idea?
In order to find the conflicting module or theme you should start with a clean install and a default theme and enable your custom modules one by one.
The problem comes from jQuery Update. I can't remove it. It uses the last jQuery available for Drupal 6 (1.3.2).
