Fix 503 Error & Monitor

My WordPress-based business site has started throwing a persistent 503 Service Unavailable error. I need you to jump in, trace the root cause, bring the site back online quickly, and then stay on as my go-to admin for ongoing health checks.

Problem snapshot
• Platform: WordPress on a standard shared host
• Recent changes: I’m honestly not sure if a theme or plugin update triggered this, so you’ll need to rule out conflicts, server resource limits, or misconfigured .htaccess/PHP-FPM settings.

What I’m expecting from you right away
1. Identify and eliminate the 503 root cause.
2. Reinstate full front-end and back-end access with no data loss.
3. Provide a concise report summarising the fix, the offending code/service, and the preventative steps taken.

Ongoing scope once we’re stable
• Set up uptime and performance monitoring (your choice of reliable tools such as UptimeRobot, New Relic, or Jetpack Monitor).
• Handle WordPress core, plugin, and theme updates safely after staging tests.
• Keep daily off-site backups and perform security scans, tightening any weak spots you find.
• Send me a brief weekly status email so I always know the site is healthy.

Acceptance criteria
– Site loads normally from multiple locations with no errors for 72 hrs.
– Monitoring alerts configured and tested.
– Clear documentation delivered for both the immediate fix and the ongoing maintenance routine.
