I don't know if I need to create a new post for this, but I am have a similar problem with DataAssist Create Email.
I am getting lots of these errors:
Deprecated: Creation of dynamic property WA_Email::$SMTPAuth is deprecated in /home/travelsaversolut/public_html/webassist/email/WA_Email.php on line 135
Deprecated: Creation of dynamic property WA_Email::$SMTPSecure is deprecated in /home/../public_html/webassist/email/WA_Email.php on line 136
Deprecated: Creation of dynamic property WA_Email::$StartBurst is deprecated in /home/../public_html/webassist/email/WA_Email.php on line 137
Deprecated: Creation of dynamic property WA_Email::$StartTime is deprecated in /home/../public_html/webassist/email/WA_Email.php on line 138
Is there a latest version of WA_Email.php I could download?
