Fix Static File Loading in Django.

My online bookstore application in Django is having issues with loading static files (CSS and JS). Despite using the correct paths in the HTML code, an error stating 'file not found' appears, causing the UI to not render correctly. I need an expert to help troubleshoot and resolve this issue.

Ideal Skills and Experience:
- Extensive experience with Django
- Understanding of static file management in Django
- Ability to troubleshoot web server issues
- Familiarity with CSS and JS

Let me know if you can help.
