Diagnose a WordPress White Screen or Fatal Error in Wyaconda

Capture the error context and recent changes, inspect available logs or Recovery Mode, then isolate plugins, themes, runtime changes, or custom code methodically.

A blank WordPress page or fatal-error message is a symptom, not a diagnosis.

Before disabling components at random, capture what failed and what changed immediately before the failure.

Preserve the error context

Record:

  • exact error text when visible;
  • affected URLs;
  • whether wp-admin works;
  • the last plugin, theme, PHP, hosting, or code change;
  • whether the failure affects all pages or only part of the site.

That information can narrow the fault much faster than guessing.

Use WordPress recovery and logs when available

WordPress includes a fatal-error handler and Recovery Mode that may let an authorized administrator enter the dashboard after certain plugin or theme failures.

Server logs and WordPress debugging can also reveal the file and code path involved.

Debug output should be handled carefully on production sites so sensitive diagnostic details are not unnecessarily exposed to visitors.

Isolate components methodically

When the evidence points toward plugins or themes, disable or switch components in a controlled way and test the same failure again.

If wp-admin is inaccessible, authorized file or hosting access may be needed to disable a broken component.

Do not delete plugins or themes before preserving a recovery point.

Check runtime compatibility

An older theme or plugin may fail after a PHP or hosting change even though its files did not change that day.

The error log and compatibility history can help distinguish that from a WordPress core problem.

Fix the cause after restoring service

Getting the site visible again is only the first step.

Replace, update, repair, or remove the component responsible so the same failure does not return at the next request or update.
