Navigation Buttons Not Working

### Navigation Buttons Not Functioning

I am experiencing an issue with the navigation buttons on the DevDocsHub web application. When I click on the **Home**, **About**, **Contact**, and **Languages** buttons, they do not direct me to the corresponding pages.

**Steps to Reproduce:**
1. Open the application at `http://127.0.0.1:8000/`.
2. Click on the **Home** button.
3. The page does not change, and I remain on the same page.

**What I Have Tried:**
- Checked the URL configuration in `urls.py`.
- Verified that the views are defined in `views.py`.
- Ensured that the corresponding template files exist.
- Restarted the development server.

Pls assign me this issue

Thank you!
