Hi,
Your issue is related to a PHP fatal error which stop the processing of the page.
Please set the "error reporting level" to "maximum" in your Joomla global configuration.
But your issue is also related to HikaShop and you have orginatly posted in the HikMarket forum section ; so I have to moved your topic in a most appropriate zone.
Next time, please be more careful when you post your message (specially when I think you know it's not related to HikaMarket because you did not provide the HIkaMarket version number).
Regards,

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