Internal Exception Error

Hello,

Every time I try to log in to my server with a couple of mods I added, an error pops up saying that my connection was lost:

Internal Exception: io.netty.handler.codec.DecoderException: io.netty.handler,codec.Encoder.Exception: java.io.UTFDataFormatException: malformed input around byte 1

I never had this problem before, I don't know if it's due to the mods or the server.

Thank you for helping .

Ok, I did that, here's the link :

And by the way, I'm on mac

Thank you

I just found out it's "The lost worlds" mod that caused this problem. It works fine now.

Thank you
