Sorry to say it, but you are being quite an idiot, saying. It doesn't work. When Vincent said, give details. He means. What exactly is going on? It doesn't work, can stem from any one of 2000+ reasons. For one, and most importantly, it could just be because you are an idiot, and then there could be so many more other reasons. Try to be specific. What kind of errors are you getting? What's the environment you are developing or QA'ing in? How are you connecting to your MySQL datasources? Are the permissions on both boxes identical to each other? Elaborate on it's not working, and quit acting like you have no tech knowledge. How would you like to hear "it's not working from one of your clients?", wouldn't you feel like smacking them with one of your baseball bats?
