I had the same problem. I do not need reviews on my site, so I copied what I wanted to remove from the file inside the includes folder and copied it to my functions.php file as follows:
// Remove reviews from WooCommerce if (! function_exists( 'woocommerce_default_product_tabs')) { function woocommerce_default_product_tabs($tabs = array()) { } }
It works for me!
