Custom modpack server won't start

[BossX]

I have created a custom modpack, and now I want to make a server for it. I have all the files (I think), yet I get this weird error when i start the cauldron server file.

Adding Accesstransformer map: CoFH_at.cfg

I got the cauldron installer, server, and cauldronbukkit file from here.

 

Here are a list of my mods:

 

The files in the 1.7.10 directory are:

 

And the file inside the ic2 directory is ejml-0.23.jar

 

Thanks in advance!

TiCTooltips is a client only mod. Try removing that. The error here:

Caused by: java.lang.NoClassDefFoundError: net/minecraft/world/World

indicates that you have a client only mod in your server mods folder.

Oh ok, I'll try this.

That solved the issue! Along with using an earlier version of COFH Core, Thermal Expansion, Thermal Foundation, and Tinker's Construct.
