title: Moving WP site to another domain
body: <p>I have simple <code>4.2 WP</code> site with theme <code>Twenty Twelve</code> and <code>Polylang</code> plugin <code>ver. 1.7.6</code>. in domain <code>mysite.co.nf</code>. Now I deciced to move it to another domain <code>mysite.newdmn.eu</code>. I have copyed all files from old domain to new one using FTP. Then have exported <code>DB</code> to <code>SQL</code> script. Have edited SQL script by replacing strings <code>mysite.co.nf</code> with <code>mysite.newdmn.eu</code> using Notepad++. Then I have imported this SQL to my new site DB, edited <code>wp-config</code> to connect to new DB and from first point of view site is running except several things:</p>
  
  <ol>
  <li>No header picture. (Actually this is not problem, but strange..)</li>
  <li>No multi language icons and it is not possible to switch between languages.</li>
  <li>Can't open one page - new server shows that it not exists. This is simple text page that looks the same like other ones. Link of this page looks the same structure like other pages.</li>
  </ol>
  
  <p>How to solve these problems? 
  And what is best practices while moving WP sites?</p>
