Does not work with Woocommerce 3.0. Under Linked Products, the select boxes are not working. Disabled Ultimate Addons and the select boxes work. Please update SELECT2.
Sorry for the inconvenience caused!
Just to let you know, the above issue is fixed in an update released a couple of days ago. Please make sure you are on the latest version of the Ultimate Addons. The latest version is 3.16.10. Here is the changelog for the same.
You should be able to see an update notification under updates in your WordPress Dashboard. If you are unable to see that, you can force check updates and proceed to fetch the latest version.
Please update the plugin and let us know if you need any further help with this. I am sure the update will encourage you to add in stars to the ratings above. :)
