I'm afraid you have asked an open-end question. Assuming that you have already established that your web server is working and able to parse PHP, and that your MySQL is running (do you know if it is?), then a lot depends on what OS you are using. If this is Windows, you can check Services, if it is LInux, you can do something similar. Then you must be using the correct port number. You have taken care of one configuration statement, but there are others in the PHP config and the web server config. When you get an error like you say you received, you have to determine what the error means. Nobody can tell you what "the web page has a programming error" means. You have to use some debugging techniques to find out WHICH part of the web page has the error, then exactly WHAT that error is! Where is that error message coming from? It doesn't look familiar to me. If you post code here in the forum, please be sure to enclose the code in [syntax=php]and[/syntax] tags, to highlight the code syntax.
