I started up the server, got all the necessary stuff out of the way and once I had the IP set up and decided to test it out, I got this as the result.
I've tried to update the client configs for Railcraft and MFReloaded then copying over to the server files, but that doesn't seem to work.
As added information that I neglected to add:
My OS System is a Mac OSX
The server I'm hosting this on is off my own computer
I'm using FTB Ultimate 1.1.0
