Hi Dale,
Please edit the class.email.php file under the include folder:
Find this line around 227:
$mime = new Mail_mime();
$mime->setTXTBody($body);
$options=array('head_encoding' => 'quoted-printable',
'text_encoding' => 'quoted-printable',
'html_encoding' => 'base64',
'html_charset' => 'utf-8',
'text_charset' => 'utf-8');
replace it with:
$crlf = "\n";
$mime = new Mail_mime($crlf);
$mime->setTXTBody(strip_tags($body));
if (strpos($cfg->getHtmlEmailTemplate(), '%message') !== false) //BSK If %message is found in the HTML email template, create HTML body MIME part
$mime->setHTMLBody($htmlbody);
$options=array('head_encoding' => 'quoted-printable',
'text_encoding' => 'quoted-printable',
'html_encoding' => 'utf-8',
'html_charset' => 'utf-8',
'text_charset' => 'utf-8');
Hope this helps :)
