عند محاولة إنشاء موضوع جديد يحتوي على السلسلة النصية “math” في العنوان أو نص الموضوع، تظهر رسالة خطأ “500 error”. لا يبدو أن الأمر يتعلق بالفئة. لدينا علامة “math”، ولكن المنشور التجريبي الذي يؤدي إلى الخطأ ليس معلمًا. إذا قام شخص ما بإنشاء منشور بتهجئة بديلة مثل “m ath”، فيمكن للمستخدم العودة وتعديل “m ath” إلى “math” بنجاح. يبدو أن إنشاء الموضوع هو نقطة الفشل.
نقدر أي مساعدة.
