Need help with crashing forge server!

I made a mod pack that works really well and that I have had no problems with but, whenever I run the forge  server with the same mods it crashes with the following error...

It seems like the "schoolmod" failed to construct. It might not be compatible with servers or you need a newer version.

The other mods seems to be fine.

[plowmanplow]

That error indicates that one or more of your mods either:

1. Is a client only mod intended for use only on the client.
2. Is poorly coded and is not properly proxying/protecting the client code in a universal mod.
