WordPress CDN caching: cache full pages safely at the edge

WordPress CI/CD with GitHub Actions: tests, builds and safe deploys
A WordPress CI/CD pipeline in GitHub Actions should test every pull request, build one repeatable release artifact, and deploy only code after approval. Keep uploads, secrets, and the database outside the repository, then switch releases with a symlink so rollback does not require copying files over the live site.

WordPress cron monitoring: prove scheduled jobs ran

WordPress LCP image optimization: make the largest image load first
A slow WordPress LCP image usually needs three things: early discovery, high fetch priority, and a file sized for the space it occupies. Find the actual LCP element first, then remove accidental lazy loading, fix responsive image markup, preload late-discovered backgrounds, and retest.

Must-use plugins in WordPress: what belongs there and how to load them
WordPress MU plugins are PHP plugins that WordPress loads automatically from a special directory before normal plugins. Use them for code that is part of the platform and must stay enabled, then keep optional features and third-party packages in the normal plugins directory.

WordPress OPcache settings: size it, check it and keep it warm
WordPress OPcache settings should be sized from the cache your PHP-FPM workers are using, not from a copied tuning block. Check the live OPcache status, count the PHP files in the active release, then make deployment resets and warm-up part of the release process.
