 * Option->General->WordPress address (URI):
    i set WordPress address (URI) and 
   Blog address (URI) as [http://www.mydomain.com](http://www.mydomain.com) but 
   sometimes later. the WordPress address (URI) changed. it’s [http://mydomain.com](http://mydomain.com)
   without “www” that’s why?

 * You mean the URL changed all by itself???

 * This is what happens if your site is available at [http://www.mydomain.com](http://www.mydomain.com)
   AND [http://mydomain.com](http://mydomain.com) – Somebody typed the second address,
   WordPress thought it was a server change and updates its configuration. Very 
   bad. Imagine someone typing the IP adress as well.
    To avoid this, you can comment
   out these lines in wp-login.php: `// If someone has moved WordPress let's try
   to detect it if ( dirname('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'])!
   = get_settings('siteurl') ) update_option('siteurl', dirname('http://' . $_SERVER['
   HTTP_HOST'] . $_SERVER['REQUEST_URI']) ); [@wp](https://wordpress.org/support/users/wp/)
   developers: please remove this “smartness”, I think this causes more trouble 
   than it helps…

 * Amen to that. It’s screwed up my site in even more bizarre ways, bringing up 
   old domains I haven’t used for months. This is a prime example of why cleverness
   is not a good thing.
