I am trying to implement a Bootstrap navbar, but it's not displaying correctly. I keep getting an error in my console that says:
https://i.sstatic.net/UwbAS.png
I've rearranged the order of my scripts in the head section, but I still can't fix this issue. Can someone please help me identify my mistake?
Here is the code I'm using:
<head>
<meta charset="UTF-8">
<title></title>
