Hi,
Please edit the file "administrator/com_hikamarket/classes/vendor.php" and replace the code:
$infos = new stdClass;
$infos->vendor =& $vendor;
$infos->user =& $shopuser;
By
$infos = new stdClass;
$infos->vendor =& $vendor;
$infos->name = $vendor->vendor_name;
$infos->user =& $shopuser;
About the mail subject, it is stored in the HikaShop database and I see that there is a little problem during the store of this information by HikaMarket.
I will see to fixed it.
But you can edit the mail content in the backend of HikaShop, the HikaMarket mails will be listed and you can override the mail content and set a mail subject.
The mail is for the moment minimalist because I don't really know which information could be useful in the email.
The "$data" variable in the mail content two objects, one for the vendor and the other for the user. So you can display a lot of information about the vendor or the user in your email.
Regards,
