Fixed
- Removed hardcoded default fonts from Target Font Families field
[2.3.3] - 2024-11-04
🔍 Improved
- Cache plugin detection messaging: Now transparent about detection limitations. Shows “may be inactive” to prevent user confusion when installed-but-inactive plugins are detected.
- Compatibility mode: Remains active for safety regardless of plugin active status.
📚 Enhanced
- Google Fonts documentation: Added Tip 2 clarifying that manual URL always takes priority over auto-detection.
- JavaScript preload warnings: Added explicit examples of scripts that should NOT be preloaded:
- ❌ Analytics (Google Analytics, GTM)
- ❌ SEO plugins (Yoast, All-in-One SEO)
- ❌ Chat widgets
- ❌ Social sharing buttons
- ❌ Non-critical third-party scripts
🔧 Fixed

require_once for is_plugin_active() function to ensure availability

💡 User Experience

🎯 Why This Update
Due to WordPress plugin loading timing, cache plugin detection may include installed-but-inactive plugins. Rather than hide this technical limitation, we’re transparent about it while keeping compatibility mode active for maximum safety.
