payment process error

[cjessop]

for some reason, on thursday, our payment authorisation seems to have stoped working.

Well thats a lie, the order can go through, although once you have entered all you details and click authorise you get this message;

Fatal Error: call to undefined function:tep_converyt_linefeeds() in /home/pkejqipg/public_html/store/includes/classes/email.php on line 149

 

this is on line 149;

$this->text = tep_convert_linefeeds(array("\r\n", "\n", "\r"), $this->lf, $text);

 

could anyone help me as im a bit blind on this one.
