Database doesn't exist, the other file it works
Question
this is really weird and I don't know why it is like this. I have my other files work fine (login, registration, and memberadd) however, on memberaddprocess file, when it try to connect to the database, it says that my database doesn't exist. The other works fine, only the memberadd process. If anyone knows why, please kindly explain.
This is my memberadd.php code
<?php
session_start();
?>

It's no easy to determine the problem, but i found a topic on mysql forum ( MySQL says a table doesn't exist, when it does ) that could be related with your problem.
It's important to make sure that there is no other mysql instance on the computer. This could result in your problem too.
