Troubleshooting Guide: Fixing Cached or Stuck Mobile Views in Twenty Sixteen

Switching themes and then switching back is a common WordPress task, but it can sometimes lead to a frustrating issue: your desktop view looks correct, but your mobile devices (phones, tablets) seem to be "stuck" showing the old theme. This problem, as reported by users of the Twenty Sixteen theme, is almost always caused by aggressive browser caching and is not a bug in the theme itself.

Why This Happens

Mobile browsers and networks are often configured to aggressively cache website data to save on data usage and improve perceived loading speeds. When you make a significant change like switching your theme, these cached versions of your site's CSS and JavaScript files can persist on mobile devices, preventing the new theme from displaying correctly. The desktop version may refresh properly because its cache was cleared or because it behaves differently.

How to Fix It: Clear the Cache

The solution involves clearing these cached files. Here are the most effective methods, starting with the simplest.

1. Hard Refresh on Your Mobile Device

A standard refresh might not be enough. Perform a "hard refresh" by clearing your mobile browser's history and cached data. The steps vary by device:

  • iOS (Safari): Go to Settings > Safari. Tap Clear History and Website Data.
  • Android (Chrome): Open Chrome, tap the three dots in the top right, go to History > Clear browsing data. Select Cached images and files and tap Clear data.

After clearing, completely close the browser app and reopen it before navigating to your site again.

2. Use a Private/Incognito Browser Window

Open a private browsing session (Incognito mode in Chrome, Private mode in Safari) on your mobile device and load your website. These modes typically do not use the cached files from your standard browser session, so they will show you the true, current state of your site.

3. Check with a Different Device or Network

If possible, test your site on a different mobile device or connect your phone to a different Wi-Fi network (e.g., a public hotspot). This can help determine if the issue is isolated to a single device's cache or a broader network-level cache.

If The Problem Persists: Server-Side Caching

If mobile devices are still showing the old theme after trying the steps above, the caching might be happening on your web server or through a third-party service.

  • Plugin Caching: If you use a caching plugin (e.g., W3 Total Cache, WP Super Cache, WP Rocket), clear its cache from your WordPress dashboard. You may also need to temporarily disable the plugin to see if it is the cause.
  • CDN Caching: If you use a Content Delivery Network (CDN) like Cloudflare, clear its cache through the CDN's control panel. Look for a "Purge Cache" or similar option.
  • Hosting Provider Caching: Some web hosts implement their own server-level caching. Contact your hosting provider's support and ask them to clear the cache for your domain.

Conclusion

A "stuck" mobile view after a theme change is a common caching issue, not a reflection of a problem with the Twenty Sixteen theme. The solution almost always involves tracking down and clearing the cache, whether it's on your mobile browser, your WordPress plugins, or your server. Start with a hard refresh on your device and work your way through the list until your site displays correctly for all visitors.
