we upgraded to version 7.9.1 and email templates which hold contact variables such as $contact_last_name are not being filled with the value when sending out an individual email.
I see those errors in the log files:
][ERROR] fromUser: Conversion of from user format Y-m-d h:i a failed

It used to work fine but now it doesn’t anymore. Any help is much appreciated.
