I'm getting this error...it's probably something easy to fix but I don't know what is wrong. Not sure why its saying plugin is disabled?:

Post your server.log using pastebin.com so i can help with the troubleshooting

where would i find that? :P do you want the startup log from a restart you mean?

Yes. I need to see why MobHunting us disabled.

It looks like your blacklist file is broken. Try to rename the file and restart your server
