    We often find that the admin and frontend areas do not load, or take forever, or get stuck in a white screen.

    It clearly is something wrong.

    How can we debug it?

    I enabled this on wp-config.php

    define(‘WP_DEBUG’, true);
    error_reporting(E_ALL); // Error engine
    ini_set(‘log_errors’, 1); // Error logging
    ini_set(‘error_log’, ABSPATH.’errors_log.log’);

    But the last logs are from August, so…

    How can we find the culprit?

    Try this 

    define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', true);
define('SCRIPT_DEBUG', true);
ini_set('display_errors', true);
ini_set('error_reporting', E_ALL);

    and then look at /wp-content/debug.log

    Thanks

    Hi Manfred Van Ursel,

    Thanks for your reply. You can also deactivate plugins by renaming the plugin folder via FTP access to troubleshoot the issue you had there. I hope it helps.
