Try changing the icon position like this:
- Go to WP-Admin > WooCommerce > Print products settings
- Change “Icon position” once
- Reload product page and look if PDF icon appears.
- If no icon appears repeat step 2
If all options do not let you show the icon, then your theme is not 100% WooCommerce compliant, because your theme developer left out important WooCommerce filters:
woocommerce_product_meta_start woocommerce_product_meta_end woocommerce_before_single_product_summary woocommerce_after_single_product_summary
- Contact your theme dev and tell them to implement the missing filters
- Create the buttons yourself in a child theme template (requires Coding Skills). Or you can contact us at [email protected] and send WP-Admin & FTP-Credentials.
