Did contacting your host solve the problem?

I realized that I had updated the php version in the beta subdirectory but not the root directory. That fixed it.
I have the same problem…I updated to php 5.4 (through Godaddy) on wp4.4.2. Still not working but hoping it’s just taking time to parse through.
@alifreeman Thanks for replying with your solution!
@eddievd refer to my link as previously posted. I would contact godaddy and tell them to update the php.ini file if the change does not happen within 12-24hrs. http://www.slickremix.com/docs/facebook-error-messages/#error-fatal-activation
