If you're getting submission notification email messages with raw or "naked" HTML tags in them, this is the fix.
Go into the
ucan-post-class.php file, and look for line 584 which shows:
$headers = "MIME-Version: 1.0\r\n" .
Change it into:
$headers = "MIME-Version: 1.0\r\nContent-Type: text/html; charset=utf-8\r\nContent-Transfer-Encoding: Quoted-printable\r\n" .
