Hope you manage to enter the website, let me know if not...
I am unable to replicate the issue with the Retina toolbar theme, using your Front-end profile on a test site. As the issue also does not occur in the Joomla admin, this suggests that something in the front-end is causing the problem.
Are you able to reproduce this on any other site?
BTW I have also noticed that access to image file system from the backend did not work with images set as main folder. I would have to allow access to file system and in this case all folder are displayed :-(
However the settings seem to work for the backend toolbar. When accessing the folders via the toolbar every path is ok, so this is only relative to the main files access from the config page or the JCE component panel.
The File Browser in the JCE Control Panel and in any media field (Images & Links etc.) using the parameters from the File Browser plugin in Editor Profiles -> Plugin Parameters -> File Browser, which you have set to
files/docs/users/$id so the File Browser is not accesing the
images folder.
Also, in Editor Profiles -> Editor Parameters -> Filesystem you have set a Directory Filter of
images/users/$id which essentially means that a user would be prevented from accessing their own folder.
