[TYPO3-commerce] Error on Checkout

[Thomas Hartwig [hartwig consult]]

Hi,

I have loaded the latest version from SVN. (Thank you to Ingo)

But now I have an error when I send a order from checkout:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result
resource in /typo3_src-4.1.2/t3lib/class.t3lib_db.php on line 783

Warning: Cannot modify header information - headers already sent by (output
started at /typo3_src-4.1.2/t3lib/class.t3lib_db.php:783) in
/typo3_src-4.1.2/typo3/sysext/cms/tslib/class.tslib_fe.php on line 2907

I don't know what to do :-(

Yours sincerely

Thomas
