شكرًا لك على المعلومات الطيبة.
جربت الطريقة المذكورة في Amazon onebox fails on my site, but works here ووجدت أن استجابة Udemy هي رمز الخطأ 403. لقد قمت حتى بنسخ موقع موقع آخر باستخدام نسخة احتياطية قديمة، وواجهت نفس المشكلة. أتساءل ما إذا كانت هناك أسباب أخرى تؤدي إلى هذه المشكلة، مثل الإعدادات؟
يرجى التوجيه. شكرًا للمساعدة.
