    Hi Stephen

    It would appear that their may be a bug in 4.9.2 when a Paypal IPN is used to process and order. Orders get processed fine if the user clicks on the link to return to the website but if they dont or they do it too late and the IPN happens then the following error occurs when the IPN postback happens. The order gets added to the database as processing correctly but no emails are sent out whereas they work fine the other way. My guess is that the error below is happening after the processing but before the emailing. As I say it only happens when the IPN is used. Nathan

    Hi Nathan,

    Please try installing v4.9.3 as it handles clearing the session better.
