[unable to check out on marketplace]

ok so apparently using the buy now option instead of buying them from my cart works as a temporary remedy, though this should be looked into regardless

[unable to check out on marketplace]

I'm trying to purchase a couple free items on the marketplace but when I click on "place your order" I get redirected to a page with the error message "the page you were looking for doesn't exist. you may have mistyped the address or the page may have moved"

if I could get some help soon that would be great, because I really just want to relax after a long day at school and a job interview
