php - I am using bootstrap to create a navbar but it isn't working,however other classes of bootstrap are working fine

Solution:

Double check the classes. I was able to get it to work following the documentation here: https://getbootstrap.com/docs/4.0/components/navbar/

Your classes are off because I was able to use everything else in your code just fine.

Answer
Solution:
You are using the wrong code for Bootstrap 4.x. Your code works on bootstrap 3.x
If you want to use the latest bootstrap version's navbar, then use this.
<nav class="navbar navbar-light bg-light">
  <div class="container-fluid"> 
   <ul class="navbar-nav">
     <li class="nav-item active">
       <a href="" class="nav-link">Home</a>
     </li>
  </ul>
</div>
