[Typo3] What's wrong with my TMailform?

[Martin Wan]

Hi all,

I use TMailform to customize my mail form. After I clicked the send button,
the email was sent successfully, but in the mean time, some warning message
was also showed on the page:

Warning: Wrong parameter count for array_keys() in
/home/cms/www/rauch-frei/pub/typo3conf/ext/pil_mailform/pi1/class.tx_pilmail
form_pi1.php on line 232

form_pi1.php:232) in
/home/cms/www/rauch-frei/typo3_src-3.8.0/typo3/sysext/cms/tslib/class.tslib_
fe.php on line 2612

What's wrong with my TMail form? Could anyone please give me some hints to
solve this problem?

I even change the php.ini, change the following line:

To:
;error_reporting  =  E_ALL & ~E_NOTICE
error_reporting  =  E_ERROR & ~E_NOTICE

But no effect occurred.

Thanks,
