Where does this code come from?

[Kraxell]

Hey guys,

i found a problem on my site, that was caused by some lines of code in my navbar-template:

<!-- jQuery Is Required -->
<script src="/path/to/cdn/jquery.slim.min.js"></script>

<!-- Bootstrap -->
<link rel="stylesheet" href="/path/to/cdn/bootstrap.min.css" />
<script src="/path/to/cdn/bootstrap.min.js"></script>

<!-- Bootstrap Select -->
<link rel="stylesheet" href="/path/to/cdn/bootstrap-select.min.css" />
<script src="/path/to/cdn/bootstrap-select.min.js"></script>

<!-- Flag Icon -->
<link rel="stylesheet" href="/path/to/cdn/flag-icon.min.css" />


<!-- jQuery Is Required -->
<script src="/path/to/cdn/jquery.slim.min.js"></script>

<!-- Bootstrap -->
<link rel="stylesheet" href="/path/to/cdn/bootstrap.min.css" />
<script src="/path/to/cdn/bootstrap.min.js"></script>

<!-- Bootstrap Select -->
<link rel="stylesheet" href="/path/to/cdn/bootstrap-select.min.css" />
<script src="/path/to/cdn/bootstrap-select.min.js"></script>

<!-- Flag Icon -->
<link rel="stylesheet" href="/path/to/cdn/flag-icon.min.css" />

I didnt know where its from, but i dont have to say that the path cause a long loadingtime, because there is no path like that on my server. Any one have an idea, for what reason its there? I deleted it and the website runs fast af.

Greetings
