Since we're doing this the right way, we are using the latest version of WordPress. But still a lot of documentation mentions this White Screen of Death. So what is it? Before WordPress 5.2 WordPress would just "die" if something went wrong. The only thing that would be presented was a HTTP 500 error, accompanied by a white screen. No further information was given, unless you had debugging enabled on your website. And since that is not recommended for a production/live site (and not the default) a lot of (new) WordPress developers would have no clue on what was happening. Basically a fatal error in PHP caused the WordPress process to quit and nothing was sent to the browser.
