If you are just running jaymod 2.1.7/8 you dont need shrubbot file , only level.db file is needed.

Once the dbfile is uploaded , go on ur server and type /rcon password !dbload (check console you will see all levels loaded) once its loaded /rcon password !dbsave.
You are now able to set levels to you and your clanmates.

Hope it's gonna help , ifnot feel free to reply
