How are you doing your AJAX call in your JavaScript? This is a normal security measure in place to prevent certain types of security issues. Also, how are you accessing your site, is there a site.dev url?

Start up the Apache server in Xampp and then go to localhost/example.html (or whatever your file is inside your htdocs folder).

Is your ajax call going to that page as well? Can you post a copy of your code?

Just want to clarify a bit for OP, the whole reason you have Xampp is so you can run a local server. If you are working off C:/xampp/htdocs/, you're not using xampp. You should be using localhost (which is basically C:/xampp/htdocs/ but gives you extra functionality).

file:///C:/xampp/htdocs/example.html

would now be

http://localhost/example.html
