 * Hi I have some notice messages on my blog dzooky.eu
    It looks like this
 *     ```
       Strict Standards: Only variables should be passed by reference in /home/dzookyeu/public_html/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_basic_singlepic/package.module.nextgen_basic_singlepic.php on line 25
   
       Notice: Undefined index: next in /home/dzookyeu/public_html/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_basic_templates/package.module.nextgen_basic_templates.php on line 150

       ```
   
 * It is also show in error_log
    I tried add `define('NGG_HIDE_STRICT_ERRORS', true);`
   to wp_config, but it does not help.
