php / mysql running?
This is a typical common Apache error message which does not tell any specifics. It would need to know more precisely what you have done and caused this.
As an example, you will need a running mysql server. You certainly don't need FrontPage extension for php/mysql. Try to upload a php file with nothing else in in it but:
<?php phpinfo(); ?>
save it as phpinfo.php and upload it to the server. Then invoke it by typing
phpinfo.php
and then check if there is an entry for php / mysql a bit further down (like in my screenshot)
