Now I am working on WordPress site that has products that are sailed with WooCommerce plugin. All works fine only after choosing the product when I fill in the all information related to the order and submit this form it goes to error 404 page. But in admin panel this order appears only when I submit the form ir goes to error page.
Any help appreciated. Was anyone who had this problem too? Thanks!
check if order received endpoints are properly set in woocommerce settings > checkout. Try saving the permalink again to flush it.
