WordPress fatal error — how to find what crashed your site

You hit your homepage and get a white screen, a generic "There has been a critical error on this website" message, or a hard HTTP 500. Admin is locked out the same way. You refresh — same thing.

Four real alerts pulled directly from a customer Slack channel. Customer name is redacted in-image. Phone status bars, timestamps, severity colors, rule names, snooze controls — exactly what arrives.

Tap any alert to view full size.
