Comment (by autotutorial):

 I'll answer you here and not in your other topic, add_filter or
 apply_filter is not available in the context of wp-config.php.
 I customized the debug based on my preferences, if ini_set works set
 WP_DEBUG_DISPLAY, default to false, check reserved words in WP_DEBUG_LOG
 and react.
 Create a folder in /wp-content/plugins/testsuper/
 add a testsuper.php file to this folder
 the plugin name is located at the beginning of the php file.
 See if you solve it?
 {{{#!php

 defined( 'ABSPATH' ) or die( 'No script kiddies please!' );
 add_filter( 'enable_wp_debug_mode_checks', function(){ return false;} );
 if ( WP_DEBUG ) {
 error_reporting( E_ALL );
 $display_conf = 0;
   if ( defined( 'WP_DEBUG_DISPLAY' ) && WP_DEBUG_DISPLAY == true )
     $display_conf = 1;
   if ( !in_array(strtolower( (string) WP_DEBUG_LOG ), array( 'true', '1',
 'on', 'false', '0', 'off' ), true ) ) {
     if( is_string( WP_DEBUG_LOG ) ) {
       $log_path = WP_DEBUG_LOG;
     } elseif (!empty( WP_DEBUG_LOG) && (string) WP_DEBUG_LOG != 'false' )
 {
       $log_path = WP_CONTENT_DIR . '/debug.log';
     }
     @ini_set( 'log_errors', 1 );
       if( !@ini_set( 'error_log', $log_path ) )
         error_log('error unknow'."\n",3,$log_path);
   }
 } else {

 Hi guys I hope you are okay, sorry I believe that null! ==
 WP_DEBUG_DISPLAY confuses ideas, when I think of null I believe in an
 undefined constant, frankly there is not the first WP_DEBUG_DISPLAY
 control.
