I’m not seeing the changes that were supposedly made to my website

The Internet can be complex. Usually if your changes are not being seen it is due to one of the following reasons:
Your browser is cached – To try and fix it, go to your website in a browser then hold the shift key on your keyboard while clicking the “refresh” button in your web browser (usually the circular arrow).  This is called a “hard refresh” where it will go back out to the server and download the latest version of your website again.
The web server is cached – For this you can power on and off your modem. You might need to leave it off for several minutes.
