Importing custom fields and going to Edit the Post Field Group all fields show successfully and am able to edit, but as soon as I save back the Field Group, I lose a range of custom fields from the end of the list.
Thank you for contacting us and I'd be happy to assist.
The editing of a custom field group can be affected, if there are many custom fields in the group and the server's PHP configuration doesn't allow it to process in one go.
To avoid this, you can follow these steps:
1. Please consult your host and request to increase the values of the following PHP settings on the server:
- PHP max input variables
- PHP post max size
2. You can divide long custom fields groups into multiple smaller field groups so that ideally, the number of total fields in an individual group doesn't exceed 10-15 fields.
I hope this helps and please let me know if you need any further assistance around this.
