Server notworking

When i started the server, and i keep on restarting it because whenever i enter, i cannot use commands, chucks are not loading, and shortly after a while i time out, but i can chat though. I did nothing to it ever since.

i just keep getting timed out

well theres nothing wrong with my connection and my plugins, its been like that ever since, i already deleted a lot and the server still times me out.
Can you guys at least set the location of the server at asia, because i live in the philippines, maybe in hong kong i guess would be great

The world is corrupt, i dont know why, in singleplayer, it crashes my game
