# The line just below this section: 'Options +FollowSymLinks' may cause problems

# with some server configurations.  It is required for use of mod_rewrite, but may already

# be set by your server administrator in a way that dissallows changing it in

# your .htaccess file.  If using it causes your server to error out, comment it out (add # to

# beginning of line), reload your site in your browser and test your sef url's.  If they work,

# it has been set by your server administrator and you do not need it set here.
