This is not a wordpress site. Also, I don't use cpanel, or phpmyadmin. I will provide ftp access and access to mysql.
1. Update shop.zick.farm to look like www.zick.farm. 
2. Switch to Neuton, and Zikketica font just like www.zick.farm.
3. Remove all the extra lines that make the website look so outdated.
4. Update login to first ask for username, then offer to send a login code, or except password. Like what ebay, or yahoo mail does.
5. Add paypal payment system.
6. Allow time for testing of website, and payment system after complete.
