Icons do not show up on Product page?

Try changing the icon position like this:

1. Go to WP-Admin > WooCommerce > Print products settings
2. Change “Icon position” once
3. Reload product page and look if PDF icon appears.
4. 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

1. Contact your theme dev and tell them to implement the missing filters
2. Create the buttons yourself in a child theme template (requires Coding Skills). Or you can contact us at support@demos.welaunch.io and send WP-Admin & FTP-Credentials.
