A current WordPress version is essential because:
- Custom Post Types rely on WordPress core functionality that gets updated
- Older versions might have security vulnerabilities
- Plugin compatibility issues are more likely with outdated WordPress
- Modern CPT features may not work properly on legacy versions
- It ensures access to the latest WordPress APIs and functions
A properly coded theme is crucial because:
- CPTs need to integrate with theme templates and styling
- Poor theme coding can break CPT display and functionality
- Theme template hierarchy affects how CPTs are displayed
- Custom archive pages and single post templates depend on theme structure
- Improperly coded themes might not support custom template files
