1.) Google: “WordPress editing functions.php” and that’ll get you there. You’ll never forget this skill. It’s the first skill an admin uses in WordPress most often.
2.) Read the WC Vendors setup guide. There’s a section on templates. Go to http://docs.wcvendors.com and enjoy
4.) Load up the WooCommerce monthly report. Copy the big number. Load up the commission report. Deduct that number from the big number. Yayyyyy.
5.) That depends, you havent said which theme you have. 🙂 🙂 Your theme may have nothing like it, all of it, or something way different. WC Vendors only interacts with the front end of your website for the Pro Dashboard and the customers leaving feedback. The rest of it is all your theme.
Cheers
