woocommerce causing errors

My site, https://www.rentmothernature.com, has been down all week. To fix this I -today- created a new MySQL database on my server, at pair com, using phpmyadmin. I added structure from previous database. I added data from backup sql file saved on 4/30 (before site problems). I then changed settings in wp-config to reflect changes (DB name & password). I removed woocommerce from wp-content file by renaming it. I then uploaded woocommerce (customized version) from saved backup. Site still does not have cart functions. I also can’t view orders in admin panel -although they are in DB.
