 I tried running
 {{{#!php
 <?php
 <?php
 set_error_handler( 'backtrace_error_handler', error_reporting() );
 function backtrace_error_handler( $errno, $errstr, $errfile, $errline,
 $errcontext ) {
         // handle @
         if( 0 === error_reporting() )
                 return false;
         $message = $errstr . ' in ' . $errfile . ' on line ' . $errline .
 ', backtrace: ' . wp_debug_backtrace_summary( null, 1 );
         if( WP_DEBUG_DISPLAY || ini_get( 'display_errors' ) )
                 echo '<br />' . $message . '<br />';
         if( WP_DEBUG_LOG || ini_get( 'log_errors' ) )
                 error_log( $message );
         return false;
 }
 }}}
 but the page loaded blank
