Mods will not load on the server, players disconnect when using mod items

[Vega Sera]

I've tried this with both the 3.0.3 versions of both server and launcher, as well as the 3.1.1 of both. Launching the game as tekkit and all. The only plugin loading on my server is essentials.

So basically what I think I might need is a step by step guide to installing tekkit on my server since I've seem to have ballsed it up somehow. I've looked throughout this forum and tried several things but nothing seems to work. Help would be greatly appreciated.

bumping, I need an answer. I'm not keen on paying for a server that I can't get working the way I want.
