Hi,
What is your HikaShop version number ?
Can you please provide some details about your configuration and your website ?
Your message/problem is not fully linked to this current thread ; it could be better to create a new one, specially if you think that there is a bug in HikaShop ; so you can provide us details to reproduce it.
Regards,

By the way, do not send me private message, use the "contact us" form instead.
