404 error when clicking on continue shopping

-- url of the page with the problem -- : seif-art.at
-- HikaShop version -- : 4.2.2
-- Joomla version -- : 3.8.11
-- PHP version -- : 7.3
-- Browser(s) name and version -- : Safari 13.0.2
-- Error-message(debug-mod must be tuned on) -- : 404 Page not found

I get 404 page not found when clicking on "contiune shopping" after a visit to the cart.

Thx for any help.

Hello Viki,

I would recommend to activate first the "error reporting" and "debug mode" settings of the Joomla configuration.
That will then display an error message on that blank page which will help us (and you better) understand what's going on and provide a solution.

Kind regards,
