in the webassist/email/waue_mem_e1_1.php file, find the following line:
$MailBody = $MailBody . "<html><head><!-- In\"+\"stanceBegin template=\"/Templates/waue html body\" codeOutsideHTMLIsLocked=\"false\" --><!-- In\"+\"stanceBeginEditable name=\"emailhead\" --><!-- In\"+\"stanceBegin template=\"/Templates/waue html body\" codeOutsideHTMLIsLocked=\"false\" --><!-- In\"+\"stanceBeginEditable name=\"emailhead\" --><!-- In\"+\"stanceEndEditable -->\r\n";
and change it to:
$MailBody = $MailBody . "<html><head></head><body>\r\n";
then find:
$MailBody = $MailBody . "<!-- In\\\\\\\\\\"+\\\\\\\\\\"stanceEndEditable --></body><!-- In\\\\\\\\\\\"+\\\\\\\\\\\"stanceEnd --><!-- In\\\\\\\\\\"+\\\\\\\\\\"stanceEnd --></html>";
and change it to:
$MailBody = $MailBody . "</body></html>";
This is a bug that should be fixed in the latest version of Universal Email available from the download center.
