Hi @sanzeeb3,
I often see the same error on debug.log.
Though I tried the solution that you showed.
[WordPress database error : Table ‘mystagedb.wp_wpmailsmtp_tasks_meta’ doesn’t exist for query SHOW FULL COLUMNS FROM wp_wpmailsmtp_tasks_meta made by require_once(‘wp-load.php’), require_once(‘wp-config.php’), require_once(‘wp-settings.php’), do_action(‘init’), WP_Hook->do_action, WP_Hook->apply_filters, WPMailSMTP\Core->get_tasks, WPMailSMTP\Tasks\Tasks->init, WPMailSMTP\UsageTracking\SendUsageTask->init, WPMailSMTP\Tasks\Task->register, WPMailSMTP\Tasks\Meta->add, WPMailSMTP\Tasks\Meta->add_to_db]
How can I recover from this error?
