Fatal error: Cannot redeclare woocommerce

hi,

I ve installed the woocommerce plugin on my website.

however, I have this issue on my frontend after the plugin being installed:

Fatal error: Cannot redeclare woocommerce_output_related_products() (previously declared in /var/www/wordpress/wp-content/plugins/woocommerce/includes/wc-template-functions.php:1093) in /var/www/wordpress/wp-content/themes/dt-the7/inc/mod-woocommerce/mod-woocommerce.php on line 87

what can I do about that ??
