This page isn’t working

In my localhost my project works fine. but here it says this page isn’t working. Is there anything not supported in free hosting or something else. I used .htaccess rules

Options +FollowSymLinks
RewriteEngine on
RewriteRule ^([a-zA-Z])/?([a-zA-Z])?/?([a-zA-Z0-9]*)?/?$ index.php?controller=$1&action=$2&id=$3 [NC,L]

is that problem?

Which page says it’s not working correctly? What are the symptoms you see?
