WordPress database error Duplicate column name ‘session_id’

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?
