Its because you have modloadermp. Not compatible, those 2. :S However if there is a mod that does require modoadermp just use forge instead, its compatible with most mods.

i think the fact you have forge and modloadermp is the issue, also tmi is a modloaer mod, not a forge one.
forge has its own form of modloader in it so the old modloader isn't needed.

try removing modloader and tmi, see how that goes

I did both of these and all i had to do was remove player api and dimensions api
