Does it crash? or just throw those errors? Does the world load up at all or are those errors during server loading up? Initial look suggests something is wrong with the CoFH/CodeChickenCore installation or version of the core mod but it's a tough guess without more info.
The world won't generate, and the server won't start because of these errors. It spits out errors while it launches, and then it just stops before it makes the world and becomes playable. I also can't seem to find a crash report or log that lists all the errors that appear during startup.
Cauldron has a old forge version, you should either downgrade the mods to version that works for that old version or you should ditch to the garbage cauldron and use something else, personally I use forge-essentials with mytown2 on a pure forge environment.
