Caching & CDN Configuration

A badly configured WordPress cache is worse than no cache at all. We set it up correctly.

Caching misconfiguration is one of the most common causes of WordPress problems: logged-in users seeing cached versions of each other's accounts, checkout pages returning stale cart data, admin changes not appearing on the live site. We configure caching and CDN delivery specifically for your site's dynamic content requirements.

Post-Mortem Report

Case Study: The Membership Site With Shared User Data

SymptomA SaaS company operating a membership site enabled Cloudflare caching following their hosting provider's recommendation. Three members contacted support within 24 hours reporting they could see each other's names, profile data, and subscription information on the account dashboard.

ResolutionCloudflare's caching had been enabled without excluding the `/account/` and `/dashboard/` page paths. These pages contained user-specific data but were being cached and served to any visitor requesting those URLs.

Business Impact

We configured Cloudflare page rules to bypass caching for all authenticated and user-specific URLs, implemented the correct cache-control headers from WordPress to signal Cloudflare's behavior, and verified that member account data was completely isolated. No further data exposure occurred. The incident was resolved within two hours of being reported.

Common questions

Questions answered.

Which caching plugin do you recommend?

We work with WP Rocket, W3 Total Cache, LiteSpeed Cache, and Cloudflare's native WordPress integration depending on your hosting environment. The "best" plugin depends on your host's server configuration, not a universal recommendation.

Do I need a CDN?

If your visitors are geographically distributed (outside a single metro area), a CDN improves performance for visitors far from your server. For local businesses serving a single city, a CDN is less critical. We assess this based on your actual traffic geography.

My site was faster before I installed the caching plugin. Is that possible?

Yes, certain caching configurations create additional overhead that outweighs their benefits on small sites, or introduce conflicts with specific plugins that slow the site down. Incorrect configuration can make a site slower. We diagnose and correct this.
