Project description:
"I need the Seraphinite Accelerator plugin re-configured so it plays nicely with my WordPress Site running on a dedicated server. Right now the site already pulls Lighthouse scores above 90 on both mobile and desktop, but as soon as I switch on “Lazy revalidation” and “Temporary cache not optimized content at initial revalidation” the W3C validator lights up with multiple errors. Turning those options off clears the markup issues but drops the mobile score to roughly 50—hardly acceptable.

Your mission is to build a clean, stable configuration that preserves my current performance while eliminating every W3C validation warning. I’m only interested in someone who has wrestled with this exact plugin before and can demonstrate deep knowledge of its advanced settings, cache layers, and the way it interacts with WordPress core, theme output, and any inline scripts or styles.

Deliverables
• Final Seraphinite Accelerator settings file (or clear step-by-step documentation) that can be imported on my installation
• Verified mobile Lighthouse score ≥ 90 after deployment
• Zero W3C validator errors on the same pages after cache warm-up
• Short change log noting any theme, .htaccess, or server-level tweaks applied

To keep things transparent I’ll supply staging access, current plugin settings, and the validation report the moment we start. I expect precise, reproducible work—not trial-and-error toggling—so please apply only if you have previous successes tuning Seraphinite Accelerator under similar conditions."
