this is a forge minecraft server, not Bukkit or Spigot. Please go to the minecraft forums or a place properly suited to help.

 

Yea @shades161 is right if you don't know how to get the new version of CraftBukkit or spigot go to www.spigot.org and you will see a post by md_5 that has around 2000 comments read it, and it will tell you how to get the newer version.
