Actually my site is already customized on the child theme, so I don’t want to start all over again. Is there anything my developer can do to make the tab appear?
By the way, should the purchase code be put in woodmart or woodmart child?
All the customization added to the child theme would remain. Please deactivate the child theme and activate the parent and check if the tab appears. If it does not, make the full backup of the site and re-upload the theme.
