Advance Custom Field or ACF plugin has option to export and import field groups. One common problem after import you will get all fields in reverse order. While writing this blog post I found the latest version still has same issue. One easy fix is, at first import the exported file in another site, export from there, now import where you wanted to import first hand. So, what happens, when you first export and import, it imported as reverse order, then when you export and import it’s imported in proper order. Funny huh !
