Hi,
I am using joomla 2.5.4 and virtuemart 2.0.6, after the creating order and confirm done, i got the message You must provide at least one recipient email address and Invalid address. for each order. can u give me a solution why this message was displaying for all orders.
Hello,
please first try yo update to a newer versions (joomla 2.5.7 and vm 2.0.10).
On your question, are you using joomla php mail function? have you make any changes? do you any third party mail plugin? Have you a right mail address on your joomla configuration or in your vendor joomla user details?
