fatally missing registry entries! crash

Me and a friend of mine cant enter my private server because whenever we enter it comes up with the fatally missing registry entries crash and we don't know what causes this here is the server log. https://mclo.gs/gRkQGXe
please help

I've found the client logs but can't open them or share them how do i do this?

okay so i opened it what is the best way to share share it so you can read it
oh and ive the problem is ender io wich i suspect it is then its completly broken since i don't have ender io installed on the server
