 * Hello
   We do not have issue with the plugin [Proxy & VPN Blocker](https://profiles.wordpress.org/rickstermuk/)
   itself, but every time we got a message error on our login page (also for the
   customer) : Warning: Undefined array key “R” in /home/xb796285/example.com/public_html/
   wp-content/plugins/proxy-vpn-blocker/proxy-vpn-blocker-function.php on line 62.
   Do you know what we should do to fix that? Or if there any CSS code so we can
   hide this message error. Thanks

 * Hello,
 * It is possible this is from a misconfiguration of your settings for the setting“
   Remote Visitor IP Header” under the Main tab of PVB Settings, What does it say
   here? It should normally be set to $_SERVER[“REMOTE_ADDR”]. or the Cloudflare
   header if you use Cloudflare.

 * Hello, 
   Yes, by default it’s set to $_SERVER[“REMOTE_ADDR”].Thank you for your
   reply.
