 * I found the following in my server error log:
 *     ```
       [16-Aug-2017 23:31:22 UTC] WordPress database error Duplicate column name 'session_id' for query ALTER TABLE cerber_log 
               ADD session_id CHAR(32) CHARACTER SET ascii COLLATE ascii_general_ci NOT NULL DEFAULT "",
               ADD country CHAR(3) CHARACTER SET ascii COLLATE ascii_general_ci NOT NULL DEFAULT "" COMMENT "Country code",
               ADD details VARCHAR(250) CHARACTER SET ascii COLLATE ascii_general_ci NOT NULL DEFAULT "" COMMENT "Details about HTTP request";
              made by require('wp-blog-header.php'), require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), include_once('/plugins/wp-cerber/wp-cerber.php'), cerber_upgrade_all, cerber_upgrade_db
       ```
   
 * Any ideas?
