    Update – WordPress Admin + CF7 issue (Cloudflare + LiteSpeed + Android)

    After extensive debugging, I can confirm this was NOT a Contact Form 7 core bug. Environment

    • WordPress (latest)
    • Contact Form 7 6.1.4 and 6.1.5
    • Hostinger (LiteSpeed server)
    • LiteSpeed Cache plugin active
    • Cloudflare enabled (DNS + proxy)
    • Android Chrome affected
    • iOS Safari working
    • Desktop working

    Symptoms

    1. In WordPress admin:
      • Tabs inside Contact Form 7 were not clickable.
      • Some admin JS interfaces appeared broken.
    2. Console errors:
      • JS blocked
      • Wrong MIME type
      • 403 errors on CF7 JS files (sometimes)
      • index.js not loading properly
    3. Behaviour differences:
      • Desktop: mostly OK
      • iOS: OK
      • Android Chrome: broken (even after purge)
      • Cloudflare Development Mode temporarily fixed it

    Root Cause

    The issue was caused by corrupted or improperly cached JS files at CDN / server / browser level.

    Specifically:

    • LiteSpeed JS combination
    • Cloudflare caching
    • Android Chrome aggressive caching

    Opening directly in browser:

    /wp-content/plugins/contact-form-7/includes/js/index.js

    forced correct JS delivery and immediately restored the WordPress admin UI.

    This confirms it was a cache-layer problem, not CF7 itself. Final Fix

    1. Disable JS Combine in LiteSpeed Cache.
    2. Add CF7 to LiteSpeed JS Excludes: contact-form-7
    3. Create Cloudflare rule to bypass cache for: /wp-admin/* /wp-content/plugins/contact-form-7/*
    4. Purge ALL caches:
      • LiteSpeed
      • Cloudflare
    5. Clear Android Chrome cache OR manually open the CF7 JS file once.

    After this:

    • WordPress admin works correctly
    • CF7 admin tabs work
    • Works on Desktop
    • Works on iOS
    • Works on Android

    Conclusion

    This is a caching conflict between:
    Cloudflare + LiteSpeed + Android browser cache.

    Not a Contact Form 7 core issue.

    Hope this helps others using the same stack.

    Additional info:
    The issue appears immediately after updating to 6.1.5, without changing anything else.
    No server errors are logged.
    Only CF7 version change triggers the problem.
