Why can't customers proceed past the add to cart section on my online store?

Hello. i use online store. For a long time, my customers cannot go beyond the add to cart section when purchasing products. I tried it too, it doesn’t accept payment. What could have caused this problem?

Hi, add another theme for your online store and try to make the same checkout steps. If it works, the problem causes by your theme. Otherwise, check your product and checkout settings on your account.
