A Warning after Installation

[CLA123]

Hi,

I get 2 lines of the following warning after the installation of the component.

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /home/asia/public_html/libraries/joomla/database/database/mysql.php on line 344

I'm not sure what it means. I had a look in the file, mysql.php line 344, it's said:

return mysql_num_rows( $cur ? $cur : $this->_cursor );

I'm wondering if you know what it means and how I can fix it.

Hi, enable debug mode to get info from database.
