Опитайте този скрипт, който тества връзката ви и отчита действителната грешка в MySQL. Може да е полезно да определите дали предоставените ви идентификационни данни ще работят или коя част от процеса е неуспешна. Тъй като го използвате на отдалечен уебхост, препоръчвам ви да кодирате твърдо потребителското име и паролата на базата данни, за да избегнете предаването им в отворен интернет.
(Забележка:Не е моя собствена работа - скриптът идва от webune.com)
