Cant move objects in object mode I have no clue what i have done that i cant move the object now i was just editing stuff in edit mode, i only added a mirror modifier, but that's it. and now i cant move it on object mode - nor connect it to the body -.

I tried most questions and turning on and off most setting that i tought it would block the movement, but i have no clue how to fix this. 

i have no clue what more to put here so i can post the question, ill add a blender file with the head obj so anyone can check what it is and hopefully help me find how to enable movement again.
in the 3D View Properties panel (N), all the Transforms are locked
