Im experiencing problems with both the com_user and com_docman extensions.

com_docman redirects every ling to www.tangojam.com/downloads. So the user cannot open any of the categories. I have default Joomla SEF handeling selected now so it is working but I can demonstrate the behavior if necessary.

Also com_user with JoomSEF has problems allowing users to register. After entering their information they are redirected to a login page that says "You must login first" I have had to disable SEF for com_login in order to allow users to register.

Any ideas on these problems? Are perhaps related?
