Basically I'm trying to follow what is suggested in the below link:
I'm trying to add a custom field called "custom_permalink" when editing a product in WooCommerce.
The data is added and a yellow frame is flashing to acknowledge. But when I click the update button for the product the custom field is not added.
I read in the below post that it can be a problem with functions.php. But I never edited that file. Can you please advice?
I added the field custom_permalink through the plugin called: Custom Permalink
This plugin adds "custom_permalink" to the Custom fields dropdown menu.
When I add a value to custom_permalink and click the "Add custom field" button it flashes yellow. But when I click the Update button to update the product the value is cleared and not saved.
What can be wrong?
