Give this log to the mod author, he's doing something badly.

Poke ChickenBones.

Logs.

Wrong mc version.

Exception in thread "Thread-15" java.lang.NoClassDefFoundError: com/jcraft/jogg/Packet

Caused by: java.lang.VerifyError: Cannot inherit from final class I say you go haunt #redpower or you uninstall the mod.

Ask your mod author.

Known, dupe of http://www.minecraftforge.net/forum/index.php/topic,7326.0.html Just Risu writing his mods in a not-so-smart way.

Ask them.

Make sure you have the same version of forge as the server.

Read your logs or read the EAQ.

Logs.

Logs?

1. WRCBE 2. and 3. RedPower.

Read EAQ, read logs, run it through google translate if you can't understand english well.

We need the ENTIRE log.

Use build 534 and MC 1.4.7, terrafirma should work. Also delete meta inf before installing. If it crashes get logs.

You don't need modloader, you don't need mlmp, all you need is forge.

Yeah, Lex, I was gonna bug you about that.

Oh one of those bukkit plugin servers. Known issue.

If the modder isn't stupid and uses config.getblock/getterrainblock/getitem there is a subset of conflict resolution.

FML log?
