I'm using this code here:

```
<?php
$post_id = 3651;
$queried_post = get_post($post_id);
$title = $queried_post->post_title;
echo $title;
echo $queried_post->post_content;
?>

```

post id 3651 definitely exists, but I keep getting a server error.

The code is so simple - I looked at it many times but can't figure out what's wrong.

Am I using outdated functions or something?
