Resource blocked due to MIME type mismatch (X-Content-Type-Options: nosniff)

Question

I am developing a web page using JavaScript and HTML, everything was working good when I have received this list of errors from my HTML page:

Answer 1

For Wordpress

In my case i just missed the slash "/" after get_template_directory_uri() so resulted / generated path was wrong:

My Wrong code :

wp_enqueue_script( 'retina-js', get_template_directory_uri().'js/retina.min.js' ); 

My Corrected Code :

wp_enqueue_script( 'retina-js', get_template_directory_uri().'/js/retina.min.js' );

Answer 2

See for the protocols HTTPS and HTTP

Sometimes if you are using mixed protocols [this happens mostly with JSONP callbacks ] you can end up in this ERROR.

Make sure both the web-page and the resource page have the same HTTP protocols.
