Hi,
The patch is not in one file. It's in each "preload" of the emails. And it's not just one line but a whole bunch, and the change is not necessarily the same in each email.
So here is a diff file of what I changed.
It's a text file inside a zip. So once you unzip it, you can open it with a text editor, or even better, with a tool like TortoiseUDiff
As an example, I changed the code:
else
$image = substr(HIKASHOP_LIVE, 0, strpos(HIKASHOP_LIVE, '/', 9)) . $img->url;
to:
elseif(!$img->external)
$image = substr(HIKASHOP_LIVE, 0, strpos(HIKASHOP_LIVE, '/', 9)) . $img->url;
else
$image = $img->url;
in the preload of the order status notification email.
