    This came up for debug. Not sure what to do with this. Did notice that user password change cannot be saved and several actions lead to a page that says critical error and action not completed.

    There is Advance cache plugin setting WP_CACHE in wp-config.php file check the line as;

    define(‘WP_CACHE’, true);

    below is the statement which need to be commented like

    // define(‘WP_CACHE’, is_file(__DIR__.’/wp-content/advanced-cache.php’));

    to prevent this error you can set to false, like

    define(‘WP_CACHE’, false);
