I've added the "show shopping cart" function in my customized files of mp_store like this:
Everything works very well except for the "Empty Cart" button. When I click on the button it turned into the loading image, but then nothing happens. Shouldn't it automatically refresh the page and show an empty cart?
I know that some parts of the function is working because when I manually hit the refresh button of the browser, the shopping cart becomes empty.
Does anyone encounter this problem? Any help would be really appreciated!
