READ THIS COMPLETELY IF YOU CHOOSE TO USE THIS FILE
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.
