Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /homep

[JCASF]

Bonjour
j'ai beau chercher une explication sur internet mais je ne trouve pas
pourquoi régulièrement quand je charge un composant, dans ce cas ci "Phoca Gallery" je vois ce genre de ligne

"Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in /homepages/17/d333222074/htdocs/monsite/libraries/joomla/database/database/mysql.php on line 293, boolean given in /homepages/17/d333222074/htdocs/monsite/libraries/joomla/database/database/mysql.php on line 293"

j'ai ouvert le fichier en question et ca correspond à ca

    public function getNumRows($cursor = null)
    {
        return mysql_num_rows($cursor ? $cursor : $this->cursor);
    } 

j'ai fait l'installation de la galerie en local et tout est parfait, mais plantage sur le site "test" en ligne
désolée de vous déranger à chaque fois et merci à vous

en lisant certains post du forum je me suis dit peut etre faut-il activer le mode débogage
et là .... horreur, malheur

je me réponds à moi meme
pour ce qui est du warning machin c'est ici la solution : installer les fichiers de la base de données "à la main"
