Plugin incompatibility
A new version may use different APIs or conflict with another component.
WordPress incident response
Did WordPress break after an update?
A white screen, fatal error, broken plugin, damaged layout or unreachable admin can come from different incompatibilities. Before blindly rolling back, it helps to identify which component introduced the problem.
What may have broken
An update can change dependencies, required PHP versions, database schema, assets or the behavior of hooks and templates.
Theme or child theme
Old overrides or custom functions may no longer be compatible.
PHP
Version, extensions or fatal errors may only surface after the update.
Database
Incomplete migrations or changed queries can break specific features.
Filesystem permissions
Incomplete updates or unwritable files can leave the site in an inconsistent state.
Cache and assets
Application cache, CDN or stale assets can make a correct release look broken.
How I troubleshoot it
We reproduce the error and isolate the component before disabling or restoring everything.
Logs and error message
Start from PHP, WordPress and web-server logs to find the exact failure point.
Isolation
Check plugins, theme, PHP and caching to find the smallest change that reproduces the issue.
Controlled recovery
If rollback is needed, target the responsible component or a verified backup instead of reverting the whole site by trial and error.
Fix the incompatibility
Update custom code, configuration or dependencies causing the failure.
Retest
Check frontend, admin, forms, checkout and relevant flows after the fix.
Technical checks
The exact scope depends on the error and what changed.
- PHP logs
- WordPress debug.log
- Updated plugins
- Theme and child theme
- PHP version
- Filesystem permissions
- Database
- Cache and CDN
- Cron and tasks
After recovery
The goal is to return to a stable version without freezing the site on outdated components.
Root cause identified
Compatible components
Verified backup
Consistent PHP environment
Updates retried deliberately
Key flows tested
