Bug details: Some of the firewall page input fields were not active.
It has been fixed and updated to the same package. If you already installed cpnginx before this time, please update this patch as follows,
wget http://files.syslint.com/src/nginx/firewall.zip unzip firewall.zip cp -v firewall.php /usr/local/cpanel/whostmgr/cgi/cpnginx
Thank you for Marcos for updating this bug information
