That seems to have fixed it. Thanks!
Having this problem as well. Gallery field 1.1.0, WP 3.8. Two of my admin users can edit captions / titles on images, but my editors can’t. Tried upgrading the editor to be an admin, but still only shows “Drag files here to upload.” Even tried creating a new admin account entirely but it has the same issue.
ACF 4.3.0, gallery field 1.0.0.
Does the gallery field update on its own, or do I need to download the latest version when I want to use it?
