Did you install c5 into a directory that mysite.com is pointing to? That would be the first thing to check. Web hosts work differently, some make you set up sites in sub-directories of your main hosting account. If your domain is not correctly aliased to the sub-directory that may be an issue, but I'm guessing here.

You should let the forum know who you are using for hosting. Someone may well have had a similar experience of setup on the same host.

If I place an index.html file in the folder and I visit the website then I can see the html page.
I think it is a problem with the hosting, I use a parallels plesk panel for configurating the hosting. Maybe someone uses this too and can help me.

Can we have a look the contents of your config/site.php file? Obviously hide username & password stuff.

<?php
define('DB_SERVER', 'localhost');
define('DB_USERNAME', 'serta');
define('DB_PASSWORD', '***');
define('DB_DATABASE', 'sertadb');
define('BASE_URL', 'http://www.serta.be');
define('DIR_REL', '');
define('PASSWORD_SALT', '***');


The DIR_REL is oke I think.
Maybe it's because it's a Windows hosting, PHP and mysql are enabled.
I can give you the link to the info.php file is this helps to?

Have you moved this from another server? Looks like pretty URIs are set to 'on', but if you're on a windows server there's no htaccess you need something different. I asked for site.php as I thought you might have set them 'on' in there, but you haven't.

If you haven't 'moved' from somewhere the installer you used has set them on by default. Probably not a great idea on Windows.

You should be able to login here.

Turn the pretty uris off and it should work. Your may still be able to facilate/enable pretty uris via a windows IIS module/extension if you definitely need that. Talk to your host.

Let us know how you get on.
