Passwort generator website

Hello. I have a problem with uploading the password generator website in Norton. The website has not been uploaded for some time. I noticed in browsers that after pressing the f12 key and opening the programmer's console an error appears: SCRIPT5650: SCRIPT5650: JSON.parse Error: Unexpected input at position:0
Is it possible that this is the reason for not uploading the page. I have checked the same on several of my computers.

Chrome also has an error on the chrome browser: Uncaught DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document.

A parser-blocking, cross site (i.e. different eTLD+1) script, https://cdn.tt.omtrdc.net/cdn/target.js, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message. See https://www.chromestatus.com/feature/5718547946799104 for more details.
