Many WordPress users try to enable Progressive Web Apps (PWA), but not everyone gets it right.
A poorly configured PWA can lead to broken offline mode, install issues, or even performance drops.
Here are the most common mistakes and how to fix them.
1. Not Using HTTPS
A PWA will not work without HTTPS.
Service workers are only allowed on secure connections.
Fix:
Install an SSL certificate and force HTTPS across your site.
2. Missing or Incorrect App Icons
Icons are required for installable apps.
If missing:
- Install prompt may fail
- App may look broken on home screen
Fix:
Use proper icon sizes:
- 192×192
- 512×512
3. Over-Caching Everything
Some users cache the entire website without control.
This causes:
- Outdated content
- Broken updates
- Storage issues
Fix:
Use smart caching rules:
- Cache static assets
- Avoid caching dynamic pages unnecessarily
4. Poor Offline Experience
Many PWAs simply show a blank page offline.
Fix:
Create an offline fallback page with:
- Basic navigation
- Cached content access
- Simple messaging
5. Not Testing on Real Devices
Testing only on desktop DevTools is not enough.
Fix:
Test on:
- Android Chrome
- iOS Safari (limited support)
- Low network conditions
6. Ignoring Service Worker Updates
Old service workers can keep serving outdated content.
Fix:
Ensure proper versioning and update strategies.
7. No Install Prompt Optimization
Some PWAs never show install prompts correctly.
Fix:
Ensure:
- Valid manifest
- HTTPS enabled
- Service worker active
- User engagement triggers exist
Final Thoughts
Most PWA problems in WordPress are not complex—they are configuration mistakes.
Once fixed, your website becomes faster, more reliable, and more engaging.
A properly configured PWA can dramatically improve user experience without changing your core WordPress setup.
