When your site shows a critical error, 500 error, blank page, or won’t load after updates, changes, or hosting issues.
Not a guarantee. Best-effort incident response.
A "site down" incident usually means WordPress cannot complete a request: PHP fatal errors, database connection failures, exhausted memory, misconfigured caching, plugin or theme conflicts, or server-side rules blocking normal traffic.
The priority is safe recovery: identify the root cause, stabilise the site, and confirm critical pages load correctly before making wider changes.
All site-down incidents are handled through our WordPress Rescue process (controlled diagnosis, safe stabilisation, verification).
A PHP fatal error or theme/plugin conflict causes WordPress to crash and show a blank page.
Learn more →Server-level failures triggered by PHP limits, .htaccess rules, permissions, or misconfigured caching.
Learn more →Database credentials, server availability, corrupted tables, or connection limits stop WordPress loading.
Learn more →WordPress, plugin, or theme updates introduce incompatibilities or trigger fatal errors.
Learn more →SSL or URL settings, Cloudflare rules, or caching causes endless redirects and blocks access.
Learn more →Firewall rules or bot protection blocks legitimate traffic or admin access after changes.
Learn more →PHP memory limits or long-running requests cause timeouts, partial loads, or admin lockouts.
Learn more →Full-page cache, object cache, or CDN rules serve broken responses or block logged-in flows.
Learn more →Check error logs, recent changes, server responses, and plugin/theme conflicts to identify the true failure point.
Stabilise access with the smallest reliable fix (safe rollback, disable conflict, correct config) to reduce risk.
Confirm key pages load, admin access is restored, and core flows behave normally before closing the incident.
You get a short summary of what failed, what changed, and what to watch to prevent repeat downtime.
Describe what you see (error message, when it started, what changed) and I'll tell you the fastest safe route to restore the site.
