We are having sweeping issues accessing our /scp from anywhere other than our main location.
We are having three issues:
1. When staff login, they are immediately redirected to login.php without any error.
2. When staff login, they are redirected to a blank-white login.php with "Valid CSRF Token Required".
3. We can only access /scp from an internal IP (even though it is located on our external site). Connecting from a satellite location on a VPN fails. Connecting over a 4G MiFi fails. I can inexplicably connect over 3G from my phone without error, though.
This error has nearly crippled one of our Departments. I have spent many hours looking through error logs, our MySQL database, our settings, and these forums. It is imperative that we fix this issue ASAP.
