mbrsolution on "[Plugin: All In One WP Security & Firewall] Secure with multi-site setup."

I have a multi-site installation and I want to use this plugin. So there is any difference to use this plugin. As we have single .htaccess file to use in this. My admin login page is showing Access forbidden! screen when I setup this plugin for my main site.
