The 'white screen of death' is when your WordPress site shows a completely blank white page - no content, no error message - usually after an update or a plugin problem. It means something stopped the site from loading at all.
Also known as: WSOD, blank white page, blank screen
In plain English
Instead of your website, visitors get a completely blank white page - no error, no message, nothing. PHP is failing so early that WordPress can't even render its error page. It's the WordPress equivalent of a total crash.
Why it matters for your business
For visitors it's indistinguishable from your site being gone - and it usually means it effectively is, for everyone. Common triggers are memory limits, a plugin conflict, a bad update, or corrupted files. It almost always requires server-level access to diagnose.
When you'll run into it
Most often right after a WordPress, plugin, or theme update - or when a new plugin is activated. Recovery usually means disabling the culprit via file access or database.
