Thanks for the info. I’m not sure what is going wrong here. If there are no errors, then perhaps they are being hidden by a server setting?
Are you able to contact your server and ask them what the issue could be?
Also, If you are able to, you can debug the issue in code. Jump into the core/controllers/field-group.php file and find the save_post function.
I would look at the loop which loops through the fields, and just echo out the name of each field. Then use a
die at the end of the loop.
Now when you save your field group, what field name does it get up to?
That will give you some data to go from.
