Hi,
Right.
There is a fix in the next version for this.
Please edit the file "administrator/components/com_hikamarket/classes/mail.php" and replace
$vendorClass = hikamarket::get('class.vendor');
$vendor = $vendorClass->get($vendor_id);
$mail->dst_email = $vendor->vendor_email;
$mail->dst_name = $vendor->vendor_name;
By:
$vendorClass = hikamarket::get('class.vendor');
$vendor = $vendorClass->get($vendor_id);
unset($mail->dst_email);
$mail->dst_email = $vendor->vendor_email;
unset($mail->dst_name);
$mail->dst_name = $vendor->vendor_name;
It should fix the problems.
Regards,
