Bukkit

I just wrote some huge message and then had to signup to make this and after I did, It deleted everything I wrote and I have to re-write it all. Well, I run Java 7 1.8 CraftBukkit on a server.pro website. I checked the groups, config, TuxTwoLib, PerWorldPlugins, and then the CONSOLE. There was an error message in the console (will be at bottom of report). I have PerWorldPlugins and it runs fine on my server. I love PerWorldPlugins a lot and I also have the plugin "HubThat" installed. I need help please! Please get back to me at [email protected] ! Thanks for reading!
