Xiaomi mi3 on Android lollipop by Ivan MMS problem

I want to say Hi first.
And now to the problem- my mi3 does not send nor receive any MMS or other file related messages (such as carrier setting messages) since I installed the Ivan rom, nobody else reported this issue on the romrom page so there is no fix, this is weird enough because everything else works perfectly (including sms, Internet etc.) i only discovered this issue by an accident.
My by someone will tell me how to fix it, because I need to sometimes send MMS :(
