 * Hello, I have a problem with a plugin that does not want to make a query :
 *     ```
       class Folio_Newsticker {
       	function Folio_Newsticker($category='64') {
       		$temp_query = $wp_query;
       		query_posts('cat=64');
       ..............
       	}
       }
       $Folio_Newsticker = new Folio_Newsticker();
       ```
   
 * I get a
 * > Fatal error: Call to undefined function is_user_logged_in() in F:\web\AnimaV2\
   > public_html\wordpress\wp-includes\query.php on line 1332
 *  because of the `query_posts('cat=64');` line : if I remove it, it doesn’t crash.
 * Also,
 *     ```
       function Folio_Newsticker($category='64') {
   
       	if (!is_home()) {
       		return;
       	}
       ```
   
 * this don’t work and that’s strange because i’m in home !
 * Does anyone have an idea ?
 * Thanks !
