Product-Category showing fatal error

Hello,
I am not able to open the product-category page. It throws a Fatal Error –

Fatal error: Uncaught Error: Call to undefined function woocommerce_product_loop() in /srv/users/serverpilot/apps/roundedneck/public/wp-content/themes/shopper/woocommerce/archive-product.php:52 Stack trace: #0 /srv/users/serverpilot/apps/roundedneck/public/wp-content/plugins/woocommerce/includes/wc-core-functions.php(205): include() #1 /srv/users/serverpilot/apps/roundedneck/public/wp-content/plugins/woocommerce/templates/taxonomy-product_cat.php(22): wc_get_template('archive-product...') #2 /srv/users/serverpilot/apps/roundedneck/public/wp-includes/template-loader.php(74): include('/srv/users/serv...') #3 /srv/users/serverpilot/apps/roundedneck/public/wp-blog-header.php(19): require_once('/srv/users/serv...') #4 /srv/users/serverpilot/apps/roundedneck/public/index.php(17): require('/srv/users/serv...') #5 {main} thrown in /srv/users/serverpilot/apps/roundedneck/public/wp-content/themes/shopper/woocommerce/archive-product.php on line 52
