Key Improvements

Error Handling

✅ File existence validation before any processing ✅ Try-catch protection around JavaScript response handling ✅ Graceful error recovery that continues to next file ✅ Detailed error messages for different failure types ✅ State validation to prevent crashes on invalid data

Timeout Protection

✅ 30-second timeout per file conversion ✅ Automatic continuation after timeout ✅ Clear timeout messages in the log

Response Handling

✅ Robust JSON parsing with fallback handling ✅ Object response support for different server responses ✅ 500 error handling without JavaScript crashes ✅ Invalid response type detection

User Experience

✅ Continues processing even when individual files fail ✅ Clear error messages showing which files failed and why ✅ Process completion with summary of results ✅ Cache busting to ensure latest fixes are loaded

Testing Recommendations

1. Clear browser cache before testing
2. Test with missing files to verify graceful handling
3. Test pause/resume functionality
4. Monitor browser console for any remaining errors
5. Verify bulk conversion completes even with some failures

Backward Compatibility

All changes are backward compatible and maintain:

• Normal image conversion functionality
• WebP serving via .htaccess rules
• Plugin settings and configuration
• Other plugin features

Only the bulk conversion robustness has been improved.

Installation Notes

1. Replace the existing WebP Express plugin with this patched version
2. The plugin will be identified as "WebP Express - CloudHost.es Fix" in WordPress admin
3. Clear browser cache if bulk conversion still shows old behavior
4. Test bulk conversion with a small set of files first
