After researching the possible culprit it seems that I must have some duplicate modfile trying to boot up at the same time, but when I search the mod folders for duplicate .zip files or .jars then I come up with nothing duplicated.


I followed the simple steps to uploading the Direwolf20 server files to my FTP server but for some reason it continues to come up with this error after trying to start the server.

Anyone have advice or a thread to point me to? I have already seen a few, but nothing seems to be helpful.

Thanks,

Sig
