I've been searching around the forums for the answer and i cant seem to have any luck. I apologize in advance if this has already been answered, but are you able to replace the MAIN jar file and with a craftbukkit jar file? if so whats the process of doing this? thanks.
You can either choose your preferred server jar in the dropdown menu in your Multicraft panel, or upload the server jar renamed to custom_server.jar More information can be found in the following resource page: https://www.hosthorde.com/forums/resources/installing-custom-server-jars.30/
