Hello,

I am using ec2 to host my multisite I keep getting this error even after I made the correct edit.

Here is what the code looks like in the wp-config.php

I cannot seem to fix this and when an user create a site it doesn't allow them to use there sub domain also I keep getting this on the domain mapping plugin settings page

I do not use the 172 IP as that is a private ip the ip that is in the field is the public ip address.

I am using a bitnami ec2 image for multisite
