When I try to select CKFinder under CKEditor File Browser setting I get a 403 Forbidden error.

I have checked cookie domain in config.php, checked user permissions, checked CKFinder directory location with no problems identified. Am contemplating a reinstall of CKEditor.

Any ideas?

NB I found this problem while trying to find out why I cannot upload a pdf or word file inline (at the bottom of some text in a body field) - I can upload it using the media button, but no link is added to my html though a default icon IS inserted into my text. There is no 'upload' option when I use the link button either!
