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.
