That's on line 36 of your config.php file so it would suggest that you have added that yourself.

Are you trying to configure Cloudflare or something like that?

 

[MattW]

This is what he's set (along with the Cloudflare stuff)

// FIX IP ADDRESS FOR PROXY
$_SERVER['REMOTE_ADDR'] = $_SERVER['HTTP_X_REAL_IP'];

 

[MattW]

Although, nginx is already configured for Cloudflare

#CloudFlare
set_real_ip_from 199.27.128.0/21;
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 103.21.244.0/22;

Thanks a lot Matt! So can I safely removed that line?

 

[MattW]

Thanks a lot Matt! So can I safely removed that line?

Yeah, and the cloudflare line below it

 

[clove28]

Yeah, and the cloudflare line below it

Alright Matt. Thank you!

I found this very useful for web hosting that uses nginx.
