Thanx so much Mike!
Its now working with single products.
We do have a couple of debug errors so child theme configurator does not work
Mostly debug errors with latest version of WPML
Notice: Trying to get property of non-object in /home/webmanager/domains/webmanager.nu/public_html/great3/wp-content/themes/enfold/config-wpml/config.php on line 674

Do you know how to fix or could we install child theme in another way?
