looks to me like you have edited the universal email server behavior of the contact form solution pack. In the server behavior you have selected the ContactForm103/contactus.php as the tepmplate file to use for the email?
in the WA_Universal_Email\WAUE_contact_1.php page, change this line:
require_once(dirname(__FILE__) . ("/ContactForm103/contactus.php"));
back to the code from the original download:
require_once(dirname(__FILE__) . ("/Templates/contactus.php"));
