Similar slugs can show the wrong post/page on visit

Overview of the issue

In some cases, posts and pages that have similar slugs may show the wrong content.

For example, if you have a post type called Books with content at http://example.com/book/title/, and you also have a post with the same slug, http://example.com/title/, you will see the wrong content when visiting these URLs.

Workaround

Our developers are working on fixing the issue.

As a workaround:

1. Go to plugins/sitepress-multilingual-cms/classes/query-filtering/class-wpml-404-guess.php, line 36
2. Replace

   	public function guess_cpt_by_name( $name, $query ) {
   		$type  = $query->get( 'post_type' );
   		$ret   = array( $name, $type, false );
   

3. With

   	public function guess_cpt_by_name( $name, $query ) {
   		$type  = $query->get( 'post_type' );
   		if (empty($type)) {
   		    $type = !empty($query->get( 'pagename' )) ? 'page' : 'post';
   		}
   		$ret   = array( $name, $type, false );
