Got this

Notice: Trying to get property of non-object in /wp-content/plugins/wp-document-revisions/wp-document-revisions.php on line 1369

Found this issue here:

function add_revision_num_to_title( $title ) {
		global $post;

		//verify post type
		if (!$this->verify_post_type() )
			return $title;

		//if this is a document, and not a revision, just filter and return the title
		if ($post->post_type != 'revision' ) {

			if ( is_feed() )
				$title = sprintf( __( '%s - Latest Revision', 'wp-document-revisions'), $title );

			return apply_filters( 'document_title',  $title );

		}

Can we change to this….?

function add_revision_num_to_title( $title ) {
		global $post;

		//verify post type
		if (!$post || !$this->verify_post_type() )
			return $title;

		//if this is a document, and not a revision, just filter and return the title
		if ($post->post_type != 'revision' ) {

			if ( is_feed() )
				$title = sprintf( __( '%s - Latest Revision', 'wp-document-revisions'), $title );

			return apply_filters( 'document_title',  $title );

		}
