It doesn't happen with default code.
I added to submit pieces custom end submit next code:
global $mosConfig_mailfrom, $mosConfig_fromname, $my;
$this->execPieceByName('ff_InitLib');
$from = '...@hot.ee';
$fromname = 'Information';
$subject = 'Advertise';
$recipient = '...@hot.ee';
foreach ($this->maildata as $data) {
if ($data[_FF_DATA_TYPE] != 'Hidden Input') {
$body .= $data[_FF_DATA_TITLE].": ".$data[_FF_DATA_VALUE].nl();
}
}
$this->sendMail($from, $fromname, $recipient, $subject, $body);
And then it gives this error!
