Atm its hard to say whats wrong as you have not posted your full code but have you tried changing the serverSide = false to true - Don't think it will make a difference but thats the only thing i can say atm

Atm its hard to say whats wrong as you have not posted your full code but have you tried changing the serverSide = false to true - Don't think it will make a difference but thats the only thing i can say atm

I would not suggest that, by setting that to true it will require the server to have the mod installed to connect to it and 90% of the time it should be false

 

You need to set online-mode to false in your server.properties.

That doesnt make sence since online-mode in server.properties requires to to have bought minecraft to connect if set to true. It should have no effect on any mod. Im not saying i know what the problem is, i dont, im just saying that im sure that is not the issue.

Yes! That worked! thanks again!
