 * Hi,
 * I just tried to use WP-Polls 2.66 and after downloading and activating the plugin
   I get the following error:
 * > Das Plugin verursachte eine Fehlermeldung 923 Zeichen unerwartete Ausgabe während
   > der Aktivierung. Sollte du Fehlermeldungen wie “headers already sent”, Probleme
   > mit der Syndizierung der Feeds oder andere Fehler erhalten, versuche das Plugin
   > zu deaktivieren oder zu löschen.
 * In English:
 * > The Plugin is causing an error 923 characters unexpected output while activation.…
 * I am using nginx and get the following information in the error-log:
 * > PHP message: WordPress database error Duplicate key name ‘pollip_ip’ for query
   > ALTER TABLE wp_pollsip
   >  ADD INDEX pollip_ip (pollip_ip); von activate_plugin,
   > do_action(‘activate_wp-polls/wp-polls.php’), call_user_func_ array, create_poll_table
   > PHP message: WordPress database error Duplicate key name ‘pollip_qid’ for query
   > ALTER TABLE wp_pollsip
