Hi All,

I have been struggling with this for some time. When attempting to send a recovery email, below error results.
I have reloaded the sale.website module, made sure the field in dbase matches the original to no avail.

What is the system checking when composing/sending the email? The problem has appeared without notice, 
only affects the cart recovery email, not invoices or quotations. 
 
Any pointers will be greatly appreciated.
Peter
