On my child theme,
I created this:
remove_action('woocommerce_single_product_summary','woocommerce_template_single_excerpt',20);
add_action('woocommerce_single_product_summary', 'woocommerce_template_single_excerpt',30);
The add_action is working, but not the remove_action
What happens is, the woocommerce_template_single_excerpt gets duplicated with the add_to_cart in the middle of the two.
I am using shopkeeper theme in woocommerce. I hope someone can help.
