I have a site with MANY custom fields. Three specific fields keep getting "unassigned." I don't know why it's happening.

Save Hide (radio)
Save Hide Notes (single line)
Ship Product (select)

Hello,

I can login your website.

Please elaborate the question with more details, provide detail steps to duplicate the same problem, where and how can I see the problem:

Thanks

Hey, Luo. Thanks for responding.

If you look at Cut Order Details, in Custom Fields, way down at the bottom should be those 3 fields (they won't be there).

Save Hide (radio)
Save Hide Notes (single line)
Ship Product (select)

If they aren't there, you can see them in Post Field Control. You'll see they're highlighted in red, because they're unassigned.

Go ahead and add them back, from "Choose From Previously Created Fields". Eventually (I don't know what triggers it), they'll become unassigned, again.

Your website PHP MaxInputVars setting value is 1000, it is not enough to setup lots number of custom fields in same field group, you need to increase it, for example, add below line in your website wp-config.php:

ini_set('max_input_vars', 3000);

Thanks, Luo! It looks like that was the problem. Fixed. Keeping an eye on it.

Again, thank you!
