Your site runs fine at my end in IE as well as Edge browser without any errors.
However, you may try below steps and see if site works fine.
1. Go to your homepage.
2. Click Page in the menu bar.
3. Select Page Properties.
4. Go to the Metadata tab.
5. In the HTML for <head> section, paste the following code:
<meta http-equiv="X-UA-Compatible" content="IE=10"/>
Now save the site and republish. Test the page on which you applied the changes and see if it works.
Thank you for checking my site, I found the security issue. It was missing the SSL certificate, once that was added the site worked perfectly.
Thank you again
