This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Debug Log


If the log is long, the latest lines are show at the top to avoid scrolling. Line numbers are shown for reference.

Logs over 5MB do not load until you confirm you are sure, or you can opt to delete the log and start afresh.

Only admins can view (or anyone you give the capability “manage_options”).

Debug Log only works if it’s enabled in wp-config.php. See

Recommended configuration:

define( 'WP_DEBUG', true );// just toggle this line to false to turn off
if ( WP_DEBUG ) {
    define( 'WP_DEBUG_LOG', true );
    define( 'WP_DEBUG_DISPLAY', false );
    @ini_set( 'display_errors', 0 );


  • Basic Screenshot
  • Warning before loading big files.


  1. Install as you would any plugin.


How do I change the number lines in Latest Errors?

add_filter( ‘debug_log_latest_count’, function(){ return 20; } );

How do I turn Latest Errors off?

Same as above but use 0… or be fancy:
add_filter( ‘debug_log_latest_count’, ‘__return_false’ );

How do I change or turn off the file size check?

Same deal. The number here is megabytes.

add_filter( 'debug_log_too_big', function(){ return 2; } );

add_filter( 'debug_log_too_big', '__return_false' );
