Not working

The Hotlink File Prevention plugin added the rule (mydomain.com was added for privacy in this post) to htaccess in the uploads folder, but it’s not working when I test the video embed on another domain.

I’m wondering if the “FilesMatch” rules in the htaccess file could be preventing the Hotlink File Prevention rules from working.

<FilesMatch "\.(?i:php)$">
  <IfModule !mod_authz_core.c>
    Order allow,deny
    Deny from all
  </IfModule>
  <IfModule mod_authz_core.c>
    Require all denied
  </IfModule>
</FilesMatch>
