On run cauldron server, openeye don't sending data to site. In logfile i'm search error(see in gist https://gist.github.com/sheynandr/30b586028a3827c12813)
Version Cauldron - Cauldron-MCPC-Plus version git-Cauldron-MCPC-Plus-1.7.10-1.1231.04.209 (MC: 1.7.10) (Implementing API version 1.7.10-R0.1-SNAPSHOT)

Looks like bukkit crash.

So the problem is solved?

No. On newest version Cauldron - OpenEye not work.
On older version - OpenEye work, but another mods not working(depend new forge version).

Hm. I'm found another version Cauldron. Mod work it, no errors.
Version - Cauldron-MCPC-Plus version git-Cauldron-MCPC-Plus-1.7.10-1.1207.01.198 (MC: 1.7.10) (Implementing API version 1.7.10-R0.1-SNAPSHOT)

Again, this is not something we can fix. It looks like exception in early initialization phase (before server is created) - it's not our responsibility to handle this exception (not even actual crash, just failure to log).
