Hi,

The support from my hoster found the problem. At all was the wrong public $tmp_path: public $tmp_path = '/usr/local/www/apache24/data/led-werbeflaechen.de/tmp';
the right was : public $tmp_path = '/usr/local/www/apache24/noexec/led-werbeflaechen.de/tmp';

The real problem was that joomla don´t print errors in the errorlog. Also breezingcommerce don´t print it. He makes an patch to breezing print this type of errors give it to me and maybe someone can use with the same problem:
