This is the way it works:all the information on your WordPress website, such as post data, page data meta information, settings for plugins as well as login information. are gespeichert in your MySQL database. The only data that isn’t saved there is media data, such as images, and the theme/plugin/core file like index.php, wp-login.php, etc.
If someone visits your site, PHP executes the code on the page, then queries the database for the data and displays the results to the user’s browser.

But, users may not see this error in the front end immediately. It is because your website is likely to be running from the cache until it runs out. For instance, at Kinsta, the majority of WordPress websites will be cached for a period of one hour on default. So, if a website remains running on its cache may seem acceptable to a user.
At Kinsta, our support team can extend the time period of your cache up to, for instance, an hour or one week if you wish. If your site isn’t updated frequently, it can improve the speed of your website’s performance since it does not have to search for new files every time the cache has expired. If you have a situation like that above the front end of the website, in most instances (unless you’ve got scripts or a part of your site breaks the cache) is likely to remain online much longer.
If visitors attempt to access your site when this error occurs, the site will show a 500 HTTP error code within your site’s logs. The same status code will show up with the words “internal server error.” This indicates that something went wrong with the server and that the requested resource could not be delivered. If everything is running smoothly, your website will display a 200 HTTP status code, which means all is well.
