Installed well but posting comments not working

Hi,

If you go to https://www.starzlet.com/Blog to post a comment to the blog post, you encountered an error like this:

This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.

For more information about HTTP errors, see Help.

Is there anything wrong with https://www.starzlet.com/Blog/wp-comments-post.php causing this?

Thanks,
Starzlet
