I have a settings page and I am saving custom fields groups to it. I have managed to save one set of custom fields, however I am trying to save another set (in a different tab).
The first set saved fine with no problems, however, when I try to save the second set, it gives a green toast bar to say it has been updated, however the custom field group remains in draft form and publish button instead of update.
What happens if you click on Publish? If the field group is still in Draft mode, you can try to deactivate all plugins and leave only Meta Box, MB AIO activate, switch to another theme.
If it still does not work, please export the field group to a JSON file and share it here. I will check this issue on my demo site.
I am trying to create a settings page for my client's site. Created the settings page : "Árak".
Also made Custom Field Groups (3) with two text fields in it, the Groups are cloneable (also "save value" is checked).
However it only saves one row of the group, and overrides it with the next one every time I try to save a new row.
