 * Hello,
    When I activate the plugin, I get the following error message: “L’extension
   a généré 186 caractères d’affichage inattendu lors de l’activation. Si vous voyez
   un message « headers already sent » (Les en-têtes ont déjà été envoyés), des 
   problèmes avec les flux de syndication ou d’autres erreurs, essayez de désactiver
   ou enlever cette extension.” In the server log, I get this also: “PHP Notice:
   Undefined variable: instance in /<server_path>/htdocs/wp-content/plugins/wp-advanced-
   search/WP-Advanced-Search.php on line 188 Not sure what to do… I deactivate the
   plugin in the meanwhile. Thank you for your help. JB

 * Bonjour,
    As-tu encore le problème ? J’ai effectué plusieurs tests mais je ne
   comprends pas trop le souci en fait. Il s’agit d’une erreur lors de la création
   de la table à l’activation, mais la ligne 188 n’a aucune raison d’être erronée.
   Mes tests n’indiquent jamais cette erreur. 🙁 Mathieu Chartier
