Probably you are trying to access your phpmyadmin. You will get this error if you have more then one “php.ini” file in your system. It is kinda conflicting. For instance i have wampserver2.0 and IIS7 together in my current system. I have activated IIS7 FastCgı method to use php on it. So it has one php.ini file at path of “c:\wamp\….” and another one in “c:\Program Files\Php” . You can get a temporary solution if you rename your php.ini file which is in your “program files” path.
That is it.
