There seems to be some problems with the loading of the plugins.
Spawning with no hunger is I think caused by Tinkers Construct, there should be a config setting to disable that.
Edit: Just tested it and created a server with the same versions that I linked. Try redownloading MCPC+ and replace the one in your server folder.
In your config folder, TinkersWorkshop.txt B:"Keep hunger on death"=true change to false
