 * Dear Team,
 * I have tried Polylang on my website, just for testing the translation. However,
   after testing , I would like to deactivate the plugin. But everytime I click 
   on “deactivate” Polyland, my website just gives me a “blank page” with this url:
   [http://mydomain.com/wp-admin/plugins.php?action=deactivate&plugin=polylang%2Fpolylang.php&plugin_status=all&paged=1&s&_wpnonce=4ca9fab093](http://mydomain.com/wp-admin/plugins.php?action=deactivate&plugin=polylang%2Fpolylang.php&plugin_status=all&paged=1&s&_wpnonce=4ca9fab093)
 * Can you help me how to deactivate Polylang?
    Thank you very much. Best regards,
 * [https://wordpress.org/plugins/polylang/](https://wordpress.org/plugins/polylang/)

 * Hello
 * It’s the same issue of this topic, when your try to deactivate Polylang, since
   another plugin or your theme use a Polylang function : [https://wordpress.org/support/topic/white-screen-after-deactivation?replies=9](https://wordpress.org/support/topic/white-screen-after-deactivation?replies=9)
 * It’s specified too in the Polylang documentation:
 * [“IMPORTANT: when using one or more of these function](https://polylang.wordpress.com/documentation/documentation-for-developers/functions-reference/),
   you *must* check for the its existence before using it, otherwise your site will
   badly break with a fatal error at next Polylang update (as WordPress deletes 
   the plugin when updtating it).”
