I (believe) I’ve found a conflict with the Jetpack plugin and ACF. Editing existing fields, and\/or creating new fields results in all of the fields “disappearing” from the back end. They don’t show when I view\/edit a field group, and the overview page lists “0” as the number of fields within that group. I cannot add new fields to that field group. Also, if I edit and save an existing field group, the existing fields are also cleared.<\/p>\n
I narrowed it down to Jetpack by deactivating all of my plugins and attempting to add a field to test field group – it worked. I then activated\/deactivated plugins one at-a-time until I got to Jetpack which exhibited the issue.<\/p>\n
