You're loading something client only on the server. Probably installed a client only mod on the server.

This doesnt make sense. if its a private game is it a server or a client?

Are you playing in singleplayer? If so one of your mods is breaking things. I can't tell you which one because it doesn't say. Make sure all of your mods are up to date. If they are and still don't work you'll have to remove them to figure out which one is causing the problem.

thank you it was a better portal mod.
