Here's what you need to do.
1. Shut down the server (either the X button or by putting in /stop).
2. Go into server.properties
3. Set the spawn-protection to that particular number.
(Note that it determines the radius of the spawn protection. Setting this to 0 will not disable spawn protection. 0 will protect the single block at the spawn point. 1 will protect a 3x3 area centered on the spawn point. 2 will protect 5x5, 3 will protect 7x7, etc. This option is not generated on the first server start and appears when the first player joins. If there are no ops set on the server, the spawn protection will be disabled automatically.)
4. Restart the server.
5. Try breaking a block.
Restart the server and try again.
