I think you want to comment out a block of code like this:

PHP Code:

    // time for the reminders
/*
    $subscriptions_reminders = $vbulletin->db->query_read("
        SELECT subscriptionlog.subscriptionid, subscriptionlog.userid, subscriptionlog.expirydate, user.username, user.email, user.languageid
        FROM " . TABLE_PREFIX . "subscriptionlog AS subscriptionlog
....
    }
    vbmail_end();
*/
    ($hook = vBulletinHook::fetch_hook('cron_script_subscriptions')) ? eval($hook) : false; 


(I didn't show the complete block, just where to put the comment start/end).
