    Hi there

    My colleague made a horrible, no good, very bad code snippet by copy pasting something off the internet. The problem is that this made Code Snippet to brick the site with error 500.

    I love Code Snippets, but it seems risky to be able to brick the site. Could more robust checks prevent this situation? The error thrown by WP:

    [10-Jan-2022 20:24:56 UTC] PHP Fatal error:  Uncaught Error: Call to a member function get_queried_object() on null in /home/site/wp-includes/query.php:44

    I fixed the snippet by disabling it via the database:

    Unfortunately, there is a limit to the number of checks we can perform. We do attempt to trial-run snippets before they are activated, but this does not apply to all situations where the code might execute, and so errors like this, where missing data is not handled correctly, are difficult to automatically prevent.

    Code Snippets includes a built-in ‘safe mode’ feature to help you deal with these issues; you can find out about it here: https://help.codesnippets.pro/article/12-safe-mode
