When the first time I started my server, I turned set the online-mode to false, everything was going fine. But after I did /stop and reboot my server, it showed these warnings. Besides, when a player rejoins the server after a long time since he exited or the server reboot, all his inventory will gone, and he spawns at the original spawn point of the world.
there is the server log:
