I modified the htaccess file to try and redirect non-WWW to WWW and it went wrong, so I reverted back to my original htaccess file.
However, it's still messed up the home page. It looks like it's trying to load fastersafer.com/www.fastersafer.com and obviously isn't getting anywhere.
Other pages work fine as it's not trying to redirect on those.
My site is http://fastersafer.com
