[CLOSED] Multiple Issues with checkout (3.0.3.6 w. journal theme)

Hi
I probably have a cache issue too
OC version 3.0.3.2 with journal theme 3
www.vinclick.it

Anybody can help me understanding if I have cache issue? Some customers were not able to complete purchases... they said the cart is refreshing or not accepting payment

Already added the code in system/framework.php but not sure if it is working

Thank you very much

In general, don't use the Journal3 framework, use a proper OpenCart with a standard-compliant theme.

Doesn't look like a cache issue as the cache control headers are set correctly. But it could depend on when you set them and what the headers were before.
