Logs, server properties, linux or windows, home or shared hosting, some type of info would really help...

 

It's a Imac, The problem is when i put the map that i had on it, it stops my server and when i'm online the world isnt there and i'm falling into a big hole and there is nothing anywhere, i put on a new map to see what would happen and the console was fine and everything looked good, i want to know how to get my old map to work again. thanks.

 

You are not giving information needed to help you.

Make sure the world in server properties is the same as the map you are placing in the folder.
