Redirect Continue Shopping link to previous page

[pdhlambert]

Hello All,

I have searched the forums and tried the replies to this answer, but still cannot get this to work.
I have VM 2.0.10 and want to change the Continue Shopping link on the Checkout page so that the use gets redirected back to the previous page they were on.

I have seen various replies as follows:

When modifying the PHP it doesn't change the link.

I am sure it is because I am modifying the wrong file or the wrong lines of PHP.
Could someone please point me in the right direction for this version of VM, and I apologise if the answer is already there!

Thanks
Paul
