به طوری کلی کنترل یک سایت از تمامی جوانب کاری بسیار مهم می باشد. در این آموزش شما با انجام یک سری کارها میتونید منابع سرور خودتون و کارکرد هرکدوم رو کنترل کنید و اگر هر کدوم از بخش ها دچار مشکلی بود بررسی کنید. این آموزش طبق گفته ی نویسنده ی اون برای وی بی 3 نوشته شده اما برای خیلی ها بر روی وی بی 4 هم کار کرده به درستی. برای انجام این کار به AdminCp خود برید. ایجاد یک پلاگین رو بزنید. admin_index_main3 رو انتخاب کنید و کد زیر را وارد کنید:
