EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

1. Download map, test if it works on local Minecraft. This will help us diagnose it as a world problem.
2. Disable all plugins. This will help us diagnose it as a bukkit problem
3. If the map opens and functions on Minecraft offline, it is indeed a bukkit problem.
4. Update your bukkit to the latest recommended build.
5. Profit.
6. If that doesn't still work, your world has issues with bukkit. Start new world! :] Or restore backup..
