Hello Sage,

Can you explain more about the issue you're having? Are you unable to see the buttons or unable to click them?

hi, thanks for reply. Please check this following link.
https://sega-int-journal.org/index.php?option=com_sellacious&view=products&Itemid=324
after that try to click on the buy now button, it just redirects you to the home page. I expected that it sends you to a kind of ongoing payment process such as paypal function, but it doesn't work at all. How can I solve the issue? Thank you

Hello Sage,

Kindly check the attached the screenshot. It's redirecting you to the cart, It's at the end of the page. And can I know which template and framework you're using? Helix or helix ultimate? As Sellacious is yet not compatible with helix ultimate.
