a bug? if Location in product,Field Group custom fields cannot more than the 32

Hi,

Thanks for reaching out.

I think this issue is related to the PHP setting max_input_vars, you can try to follow this tutorial to fix the issue https://metabox.io/wordpress-custom-fields-not-saving-increase-max-input-vars/

unsuccessful。

1.system default，if custom fields more than the 32 fields can use in post.
but unuse in product. Settings Location product will jump to post.
So I don’t think the max_input_vars matters

2.i upload ini_set ('max_input_vars', 10000 ); to wp-config.php but unsuccessful.

Hi,

If you are using the builder, please try to increase the value to a higher, such as 2-300k.

Or please don’t save the field group, after creating the fields, please generate the PHP code and paste it to the file functions.php in the theme/child theme folder to create the meta box and custom fields. Refer to this documentation https://docs.metabox.io/extensions/meta-box-builder/#getting-php-code

Let me know how it goes.
