Since I installed the new theme update, I still see a button with "add to cart" with the sold out products. Before that it was a button with "read more".
How can this be restored?
See link below.
Please send us WordPress dashboard access privately thru the contact form, which is on the right side at http://themeforest.net/user/muffingroup#contact and we will check what might be the reason.
Please attach a link to this forum discussion.
Sending incorrect or incomplete data will result in a longer response time.
Therefore, please make sure that the data you are sending are complete and correct.
The root cause is your child theme.
After switching to the parent theme it is correct.
You should contact your web developer to correct that.
This has been resolved and can be closed :)
