Hi,

As we can see, you are using our theme on a second website so you need to purchase one more license for it and add it in your account on our website.

As for the error, 500 Internal Error says about some issue on the server and can be caused by different things. Anyway, to understand its nature you need to see your server error logs or enable PHP error display on the website. If you can’t do this, you need to contact your hosting provider for help in this question. Here is an article that may help you understand the error better http://www.wpbeginner.com/wp-tutorials/how-to-fix-the-internal-server-error-in-wordpress/
