I'am not able to get joomSEF to work.

When I install it, and activate "Search Engine Friendly URLs", all my links are genererating 404 error's, as it says in the FAQ i check access to .htaccess and all looks ok.

the options I set in the .htaccess
# mod_rewrite in use
RewriteEngine On

# Update Your Joomla! Directory (just / for root)
RewriteBase /


What are my options to further troubleshout this problem?
