 * So i have checked the class_wp_query.php but it looks like that there is no error.
 *     ```
               foreach ( $keys as $key ) {
               if ( !isset($array[$key]) )
                   $array[$key] = '';
           }
       ```
   
 * Can anyone help me?
 * Thanks in advance.

 * 268,435,456 is 256MB. The issue is that the query uses a lot of memory. You could
   try to bump it up a bit. However, this may be the result of your theme or a plugin
   just asking for too much.

 * Thank you for your quick answer.
    I tried to increase the memory up to 256M but
   it dont work. The info.php say it is still on 128M…

 * This may be a plugin or theme conflict. Please attempt to disable all plugins,
   and use one of the default (Twenty*) themes. If the problem goes away, enable
   them one by one to identify the source of your troubles.
