not hikaserial in order but yes in perfil

-- url of the page with the problem -- : extrevalor.com
-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.6.2

Sorry for my English, I'm using google translator.

When a user purchases a product on the web you receive the mail, but the serial does not appear (before if I did). However in the backend when I check your purchase if you have assigned a serial purchase.

Not from that moment I stopped working (that update joomla or hika).

I have reviewed and looked manuals and I have not seen anything, not if I'm already locked or I do.

I ask for help because the problem is causing me that with every purchase has to send the serial manually.

Thank you.
