Modding help

[SirSiege]

Hey everyone I am rather new to all of this and I really need some help lol. See I had some mods on my server, then this mournign I added CoDaM. Now the problem is since then all my previous mods have completely stopped working (only 2 mods). I was just wondering if anyone here could explain the reason for this and a way to fix. Any help will be greatly appriciated.
