I understand that wordpress development SE doesn't welcome plugin question-- including woocommerce plugin. If you look at the first page of woocommerce tag, you will find that
OFF TOPIC. Questions specific for this e-commerce plugin have their own forum at https://wordpress.org/support/plugin/woocommerce.
But the above https://wordpress.org/support/plugin/woocommerce is a dead link, can someone fix this? Even though I can edit it, but I don't know what to put in.
