When I click on "using different billing address" button on the checkout page, it clears out all the details I have entered in before. The same thing happens when I decide not to use a different billing address, the details are cleared again.
I have been searching online and found some posts had the same issue but nobody offered any solution. I tried to alter the code to fix this, but unsuccessful so far. I'm wondering has anyone run into this before who knows how to fix it please?
Thanks very much.
