I've solved the problem, it was for some reason OceanCraft and a couple other client side mods. I appreciate the replies.

I need some help. I've made a modded server with the mods from my custom modpack(http://www.technicpack.net/modpack/bigworldpack.709394). However, I've removed the client side mods I know of but it keeps giving me this error: ---- Minecraft Crash Report ---- // Uh... Did I do that?
