Troubleshooting

If images don't show resize handles:

• Check that showImageResize prop is true (default)
• Verify the custom CSS is loaded
• Check browser console for errors

If crop modal doesn't appear:

• Ensure onImageUpload function is provided
• Check file input accepts image types
• Verify upload endpoint is working

If styles look wrong:

• Clear browser cache
• Check that custom-editor.css is imported
• Verify Chakra UI theme is loaded
