Hello tada,
Thanks for your answer.
That’s exactly what I have done: granting column privileges to ID and user_email only. This part works fine.
My understanding is that get_the_author_meta(‘user_email’) would still request access to all columns and for this reason calling it fails. I need an alternative to that so I can just access user_email without a need to grant access to all columns.
As for the code it is just a call to get_the_author_meta(‘user_email’). I haven’t tried anything else because honestly I don’t know from where to start right now.
Thanks!
