I need my website checkout page fixed. I hired a Freelancer on this site to redesign our website. They added in a mega menu top navigation and added in mobile menu then left for the weekend.
Everything looks okay however, when the customer adds to cart and clicks check out the shopping cart page is ok then click to go to one page checkout there is a 404 error populating which prevents my customer from checking out.
Please do a test by adding a product on my website here and checkout so you can see what the issue is. View my website here [url removed, login to view]
