[manel_mato]

Hi everybody,

I've done the update to virtuemart 3 and the old registered buyer don't receive the purchase confirmation mail or the invice mail too. This problem doesn't exist if is a new buyer.

Anybody can help me?

Thank you,
Manel

Oh I'm sorry I've updated from virtuemart VM 3.0.10 to VM 3.0.16 in joomla 3.5.1 and when a new user is registered in the web no problem but when and old user try to do a purchase don't receive conformation mail or can't change the password.

Thank you in advance.
