Performance and Cache

Performance and Cache Settings Guide

Applies to: Current VideoHub360 theme package

Theme Performance Options

Go to VH360 Theme → Appearance to configure Asset Minification, Lazy Loading, and other available theme performance controls. Enable minification only when the server can write the generated files and after testing frontend scripts, Studio, and the Customizer.

Theme Transient Cache

Go to VH360 Theme → Advanced to set Transient Expiration and use Clear All Theme Cache. This clears theme-managed cached data.

Other Cache Layers

Theme cache clearing does not purge:

  • a WordPress page-cache or optimization plugin
  • host-level full-page or object cache
  • CDN cache
  • browser cache
  • installed-PWA service-worker cache

Purge each layer separately when diagnosing stale output.

PWA Cache

An installed PWA can retain older assets on a specific device. After a major PWA or navigation update, close and reopen the app, refresh the browser version, and use the PWA troubleshooting/reset tools where available. Reinstall only when normal update and cache-reset steps fail.

Safe Optimization Order

  1. Configure and test the site without aggregation or delay features.
  2. Enable one optimization at a time.
  3. Test login, dashboard tabs, comments, menus, video playback, Studio, PWA installation, and checkout.
  4. Exclude dynamic REST, AJAX, Studio, login, dashboard, cart, checkout, and webhook requests from full-page caching when required by the cache product.

Troubleshooting

The frontend shows old settings

Clear theme cache, page cache, host/CDN cache, and browser cache in that order.

Studio or dashboard controls stop responding

Disable script delay, combination, or aggressive minification for the affected assets and retest.

The installed app differs from the browser

Reset or update the PWA cache on that device. Do not change viewport or safe-area code as a cache workaround.
