Everytime I try to start my server I get this error:
** please restart the server and if the problem persists, remove the directory './world/players'
[03:24:36] [Server thread/INFO]: Stopping server
[03:24:36] [Server thread/INFO]: Saving players

Please help! I need the server for a friend tonight as it is her birthday!! 
So that the console said. Download the map and delete the players Ordner. Your items will reset but the map will be the same.
Just read the console log. It says that the players directory is outdated. Remove the players directory and upload your world again, then it should work.
