I've just checked up the path for pages in Settings:
It's:
/pages
In Config.php, I have no double slashes:
<?php
define('DB_TYPE', 'mysql');
define('DB_HOST', 'localhost');
define('DB_USERNAME', 'username');
define('DB_PASSWORD', 'pass');
define('DB_NAME', 'user_wb');
define('TABLE_PREFIX', '');
define('WB_PATH', dirname(__FILE__));
define('WB_URL', 'http://www.homepage.com');
define('ADMIN_PATH', WB_PATH.'/admin');
define('ADMIN_URL', 'http://www.homepage/admin');
// some mail provider do not deliver mails send via PHP mail() function as SMTP authentification is missing
// in that case activate SMTP for outgoing mails: un-comment next line and specify SMTP host of your domain
// define('WBMAILER_SMTP_HOST', 'mail.example.com');
require_once(WB_PATH.'/framework/initialize.php');
?>
What I don't understand, the error occurs only for the same page and when I create a new page in the main navigation, I get no errors.
But I notice that this page goes in a submenu "About Us" (for instance) and the directory on the server is called: "about-us".
So:
--About us
-------Curriculum Vitae
-----------My Name
(the page with problems)
The page "My name" crashes when I click on it and I get this 404 Found Error.
