من یک افزونه وردپرسی دارم که مال افزونه Restrict-Content-Pro هست که کار این افزونه محدود کردن تعداد دانلود کاربران هست تنها مشکلی که بااین افزونه دارم این هست که وقتی تعداد محدودیت رومشخص می کنی افزونه به خوبی کارمیکنه وقتی به تعداد 0رسید افزونه شروع به اضافه کردن به سبد خرید میکنه یعنی اگه محصول رایگان باشه براحتی اجازه خرید ودانلود رو میده حالا تغییر یکه من میخوام این هست که وقتی تعداد محدودیت تموم شد به یه صفحه خاص منتقل بشه:
