You install WP Mobile Menu for better mobile navigation. On phone, you see desktop menu. Huge links. Hard to tap. That is frustrating because mobile menu does not work.
A common issue is that the plugin does not detect mobile devices correctly. Or theme enforces desktop menu regardless. The plugin is not broken. Device detection is failing.
Why WP Mobile Menu Shows Desktop Menu on Mobile
WP Mobile Menu checks user agent to detect mobile devices. If detection fails (new device, custom browser), plugin shows desktop menu. Also, if theme outputs desktop menu unconditionally, mobile menu never replaces it.
This is not WP Mobile Menu being bad. Device detection is imperfect.
The Most Common Mobile Menu Failures
- New mobile device not recognized (user agent outdated)
- Theme hardcodes desktop menu (no replacement)
- Cache plugin serves desktop HTML to mobile
- User switches between desktop and mobile mode
- Plugin disabled on specific screen sizes
Cache often serves wrong menu.
How to Fix WP Mobile Menu Detection
- Go to WP Mobile Menu → Settings → Display
- Enable “Force mobile menu on all devices” (test only)
- Set mobile breakpoint to 768px (not user agent)
- Enable “Hide desktop menu on mobile”
- Clear all cache
- Test on real phone
Breakpoint-based detection is more reliable.
How to Exclude Mobile Menu from Cache
Cache plugins serve same HTML to all devices. Configure cache to serve different versions:
WP Rocket: Settings → WP Rocket → Advanced → Mobile cache → Enable separate cache for mobile.
LiteSpeed: Cache → Mobile → Enable mobile cache.
Mobile cache serves correct menu to phones.
Alternative: Use CSS Media Queries Only (No Plugin)
Instead of plugin, use CSS to transform desktop menu to mobile:
@media (max-width: 768px) {
.menu { display: block; }
.menu li { display: block; width: 100%; }
}
CSS-only mobile menu always works.

Final Thoughts
