WordPress – The requested URL /wp-login.php was not found on this server

I created a site on my local pc …/htdocs/wordpress/(all the sites files). Now, I need to transfer my site to the server. I am using FileZilla.

I transferred all my sites files to the /www directory, the wp-config.php points to the database correctly. I also imported my local database to the server database and changed the wp_options table’s home and siteurl values to this url: http://wwwhello.com/.

Then, in the WordPress admin dashboard Settings page I changed the Site Address (URL) and WordPress Address (URL) to the same http://wwwhello.com/. And then I get logged out and get this error:

The requested URL /wp-login.php was not found on this server.

I cannot access my site online nor my admin dashboard. What is the issue?

I tried renaming the .htaccess file to see if the problem is in it but it didn’t help. In the wp-config.php I included these lines:

define('WP_HOME','http://wwwhello.com/');
define('WP_SITEURL','http://wwwhello.com/);

It didn’t help.
