Restore Lightning-Fast WordPress Speed

My WordPress site crawled to a halt right after moving to PHP 8.2.35. Both the public pages and the admin area now take ages to load. I’m looking for someone who can methodically track down what went wrong—whether it’s the PHP upgrade, the many tweaks in our custom CSS, a mis-tuned LiteSpeed Cache configuration, or something else—and then bring the site back to its previous snappy state.

I’d like you to work step by step: first diagnose, then apply safe, proven fixes, validating each change as we go. The end goal is simple: instant page loads and CLS scores squarely in the green.

Key tasks you’ll tackle:
• Run a full performance audit (server logs, PHP error logs, MySQL, PageSpeed Insights, Lighthouse, GTmetrix)
• Isolate bottlenecks introduced by PHP 8.2.35, custom CSS, and current LiteSpeed Cache settings
• Optimise or roll back any problematic code, queries, or styles
• Fine-tune LiteSpeed Cache rules, object caching, and CDN integration if needed
• Re-test, compare before/after metrics, and document exactly what was changed

You should be comfortable with WordPress core, theme/plugin conflicts, PHP profiling tools, web-vitals tuning, and LiteSpeed-specific optimisation techniques.

Deliverables will include:
1. Diagnostic report identifying root causes
2. Implemented fixes and configuration updates
3. Post-optimisation metrics proving speed gains and green CLS

If this systematic approach to restoring high-performance WordPress sites is familiar territory for you, I’m ready to get started right away.
