FTB Server Issues After the Update - cpw.mods.fml.com"mon.MissingModsException

[chzos]

I manually updated all of my server's mods to the latest ones that were downloaded through the FTB launcher, and updated Forge so Soulshards 1.21 could run.
When starting my server this is the error crash report I get:

cpw.mods.fml.common.MissingModsException
at cpw.mods.fml.common.Loader.sortModList(Loader.java:237)
at cpw.mods.fml.common.Loader.loadMods(Loader.java:460)

Thank you for any assistance given. Even if you just point me in the right direction.

Looks like a lot of MindCrack servers have been having issues with the new update.
My server host just e-mailed me this morning to tell me that they have updated the FTB modpacks,
I'm just about to hop on Minecraft to confirm this.

The error fixed itself when I reverted back to SERVER VERSION 4.
Unfortunately all your players have to revert back to Version 4 until the mods release a fix for v6.
