 * Hello
    I have WordPress 5.6.4, my site is [https://choeurpolycantus.fr](https://choeurpolycantus.fr),
   I use WP-Optimize 3.1.11 and I have this warning in the top of the page of the
   plugin:
 * “Warning: Declaration of WP_Optimize_Notices::url_start($html_allowed, $url, 
   $https = false, $website_home = ‘updraftplu…’) should be compatible with Updraft_Notices_1_0::
   url_start($html_allowed = false, $url = ”, $https = false, $website_home = NULL)
   in /homepages/6/d737435129/htdocs/clickandbuilds/Polycantus/wp-content/plugins/
   wp-optimize/includes/wp-optimize-notices.php on line 303″
 * What is the problem ? What can I do to have this warning removed ? But the plugin
   seems to work properly. Thank you Denis
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwarnin-wp-optimize%2F%3Foutput_format%3Dmd&locale=en_US)

 * [@mars29dr](https://wordpress.org/support/users/mars29dr/) In wp-config.php file
   Can you please try to
 * Replace
 * `define('WP_DEBUG', false);`
 * with this:
 *     ```
       ini_set('log_errors','On');
   
       ini_set('display_errors','Off');
   
       ini_set('error_reporting', E_ALL );
   
       define('WP_DEBUG', false);
   
       define('WP_DEBUG_LOG', true);
   
       define('WP_DEBUG_DISPLAY', false);
       ```
   
 * and check if it helps to fix the issue?

 * I think you have a very old version of UpdraftPlus (or something else from the
   same family) installed; if you update it, all should be well.

 * This has been traced: it happens if you have WP-Optimize and MetaSlider. We have
   adjusted our next release so that it won’t happen.
 * It’s best not to send PHP programming notices to the browser; you should configure
   your hosting to instead send them to a log file.
