For those of you who have recently updated Maltego to 4.2. version, Social Links Entities may fail to display names, but only ID’s (i.e. just numbers).
This is our short how-to if such a problem occurs.
Open Maltego and go into Entities --> Manage Entities and delete all SocialLInks Entities.
Then turn back to Transform Hub and re-install Social Links transformation set (uninstall and install again)
If the problem still occurs, please contact us at email@example.com. We are here to help!
