Hi John, I upgraded to V7 from 5.3. I did it sometime ago but never realised the ACF data was missing it was just something I did.
All the same winding back to V5.3 ensures everything is working fine.
I am using the latest version of ACF too Version 4.4.12
I have also double checked the fields show on PHP V5.3 but not 5.4, 5.5, 5.6 or 7
I’ve taken your advice and submitted a bug report its all a bit odd.
