Cannot join Squads, Invite other players or see Friends Onlline

[(PSN)KaciaTheDemon]

Ok, so I cannot seem to invite other players to my Squad as it says 'Cannot deliver invitation' and I cannot receive invitations because for friends it says 'It appears that this player is Offline'. I've tried reinstalling Warframe and it hasn't done anything, I've even rebuilt the database on my PS4 but that hasn't worked too. My Matchmaking is set as Public and my PS4 account is not on offline mode either. It all started when I was doing a Relic mission and as we were picking Rewards my friend's PS4 is quite laggy so it made him leave the Squad. It said 'host migration in progress' and it loaded me back into the mission, it gave me another option to pick a reward of an item so I did. I loaded back into my ship and I got a duplicate of Vauban Prime Systems, so i deleted them both to see if anything would happen and nothing has worked. Please help.
