title: Public DNS has changed and now my wordpress site is broken
body: <p>I set up an AWS EC2 micro instance with LAMP and installed Wordpress and a theme and activated the child theme. I have made numerous changes to the site and all was good. </p>
  
  <p>I then resized the instance. I did not have an elastic IP set up. I now have a new public IP. </p>
  
  <p>I can access the instance via SSH and everything works. But, I cannot load the site via its new public IP. It just keeps loading and timing out. </p>
  
  <p>My security groups are fine, all are open. </p>
  
  <p>I have tried following the article on changing the url but none of those suggestions work (<a href="https://codex.wordpress.org/Changing_The_Site_URL" rel="nofollow">https://codex.wordpress.org/Changing_The_Site_URL</a>)</p>
  
  <p>I believe that I need to search and replace my old url with the new one. But I can't find the old url and the command <code>[ec2-user ~]$ curl localhost | grep wp-content</code> does not work. </p>
