Hi @robinw
Thanks for the follow up. We can confirm that the JSON response looks good, but it holds no data.
It looks like you have a plugin / theme code which is hooking into the get_posts function and modifying the args. This can sometimes be the case with a members plugin which restricts posts based on a user level.
Can you please try a fresh install of WP, ACF and Gallery field? Does it work correctly? Try adding in your other plugins / theme one by one until you hit the issue.
