source URI is not allowed in this document

Question

I am working on a website on my localhost and suddenly I'm now getting this errors.

I get this error on Firefox

<script> source URI is not allowed in this document

And nothing on chrome,` but if I try using the files code, I get:

Application Error: There was a problem getting data for the application you requested. The application may not be valid, or there may be a temporary glitch. Please try again later.

It is basically for: https://connect.facebook.net/en_US/sdk.js.

The browser doesn't even send a GET request for the file.

Everything used to work perfect before. Not sure why I'm getting this.

Answer 1

I had an extension installed on both of my browsers. It was preventing it from loading.

If you have any VPNs, hide-tracking extensions, then it needs to be disabled.

In my case it was Disconnect firefox/chrome extension.
