Just as a build on @markE's answer—if you want to create a local server. You won't have this error on a local server.

If you have PHP installed on your computer:

1. Open up your terminal/cmd
2. Navigate into the folder where your website files are
3. While in this folder, run the command php -S localhost:3000 ← Notice the capital 'S'
4. Open up your browser and in the URL bar go to localhost:3000. Your website should be running there.

If you have Node.js installed on your computer:

1. Open up your terminal/cmd
2. Navigate into the folder where your website files are
3. While in this folder, run the command npm init -y
4. Run npm install live-server -g or sudo npm install live-server -g on a mac
5. Run live-server and it should automatically open up a new tab in the browser with your website open.

Note: remember to have an index.html file in the root of your folder or else you might have some issues.
