I have created a custom field for woocommerce products using Meta Box. Shortly after that I decided to rename the custom field and therefore also adjusted the ID. Unfortunately, since then I have the problem that the field can no longer be filled.
I enter the content of the Woocommerce article into the field, save the product and after reloading the page the field is empty again.
How can I solve the problem?
Deleting and recreating the field (with the same name and ID) did not solve the problem.
Thanks already once.
