Yeah One More Day and One Moment In Time erased the world's knowledge of Peter's identity. Doctor Strange performed a spell along with Tony Stark and Reed Richards in One Moment in Time that wiped out the knowledge. Only MJ at that point retains knowledge because Peter had a weak moment and pulled her outside of the bubble (i could be misremembering things).
Right now in the proper 616 reality only MJ, Carlie Cooper, and the Fantastic Four (Johnny had Peter reveal his identity to them) are aware of his identity. I think also his New Avengers teammates know who he is, and Captain Marvel (Carol).
Also after the events of Spider-Island the spell has begun to weaken itself according to Doctor Strange, through Peter's antics during that arc.
