Uploaded world doesnt have my buildings

Hello,

I decided to upload a world to my server. When i logged in the map was empty. I can still play on it on singleplayer and it has buildings in it. Please I would like some help since my friends and I spent a long long time working on it.

Thanks.

I'm at the same coordinates.

as a .rar

I'll try as a zip then. I'm gonna update the thread if it works.
