 * Hi,
 * Looks like this plugin just doesn’t work for me. I install it, activate then 
   copy the shortcode [mr_rating_result] to have the rating box somewhere on my 
   page.
 * This is what I had :
 * `Fatal error: Uncaught Error: Call to a member function get_default_language()
   on null in /home2/website/public_html/wp-content/plugins/multi-rating/includes/
   class-api.php:729 Stack trace: #0 /home2/website/public_html/wp-content/plugins/

   rating/includes/class-api.php on line 729`
 * If I check the box “Pages” in the Post Types option i have a white page and my
   site stop workng.
 * So how can I make it works ?
 * Thank you,

 * Hi Florent,
 * A fatal PHP error is returned because the global $sitepress variable is unexpectedly
   null. This global variable is set by the WPML plugin. Do you have WPML enabled?
   Or the Polylang plugin by any chance?
 * Thanks,
    Daniel

 * Hi Daniel, yes I have Polylang installed. How can I set this variable to a non-
   null value ?
 * Thanks!
