The request
“We have Klarna on-site messaging enabled. It displays banners on certain pages but on one page in particular it errors, and on the product page it's not showing at all.”
Messaging in the wrong places.
The approach
We corrected where the Klarna messaging appears: under the price on product pages, in the cart, and removed from pages where it was erroring.
What we shipped
Klarna messaging under the product price
Messaging in the cart
Removed from pages where it errored
No console errors
