title: Can't remove or edit post after changing domain name
body: <p>I recently changed from one domain to another, in that new domain i copied my wordpress files/databases, everything was working fine, until i found some posts without any categories in it, when i tried to edit thoose "categoriless" posts i found a weird error, they can't be changed.</p>
  
  <p>Any modifications that i do gets saved on database as a new post version ( Wordpress even warns me that there is a newer version of the post ), but i simply cannot use the new version.</p>
  
  <p>The only thing that i managed to alter in post os the slug, after moving the post to trash the sluged is updated to something like this:
  example.com/my-wordpress-post__trashed ( This post is still accessible in the website )</p>
  
  <p>I deactiveted all the plugins and even changed the theme, but the problem persists, any ideas on where should i look to find a solution?</p>
