 * Hi there,
 * I noticed the error shown on this screenshot [http://prntscr.com/iuq1pq](http://prntscr.com/iuq1pq)
   
   I deactivated your plugin and reactivated it but the issue persists. I’m using
   version 6.5 in Standard mode, even the problem occurred in Legacy mode. However,
   it disappear when I deleted your plugin. Please kindly help me to resolve this
   issue.
 * Cheers.

 * Hi!
 * Those message are shown due to a bug in your active theme. The theme wrongly 
   performs some output before all plugins are completely initialized. Ask the theme
   developer for help.

 * Hi Gioni,
 * Thank you for your prompt reply, I do appreciate.
    However, do you have any alternative
   suggestion to help resolve this issue? This is because I am using a heavily customised
   out-dated BuddyPress Theme and I am not sure if I can any help from them.
 * Besides, I noted you provided solution to one of your Users – sanniel who had
   a similar problem about two days ago on this thread [https://wordpress.org/support/topic/v6-5-cause-php-output-in-header/](https://wordpress.org/support/topic/v6-5-cause-php-output-in-header/)
 * Alternatively, is there a possibility to rollback to v6.2 which according to 
   sanniel didn’t show the output error. But this would be my last option due to
   security concern, I would be happy for a better solution.
 * Please kindly help me.
 * Thank you.

 * This fastest recipe should work. Add the following lines to the wp-config.php
   file. The file is usually located in the root folder of your WordPress.
 *     ```
       ini_set( 'display_errors', 0 );
       define( 'WP_DEBUG', false );
       ```
