Can't read properties of null error upon opening the website

When I am opening the website, I get this error.

Please use text so it can be searched. Firefox gives this in console;

Uncaught TypeError: document.querySelector(...) is null
    <anonymous> https://www.sugarlabs.org/js/main.js:15

The lines causing the problem are var h = document.querySelector('.logo1').innerHTML; h = h.replace(/033cd2/g, COLORS[color][0]); h = h.replace(/78e600/g, COLORS[color][1]); document.querySelector('.logo1').innerHTML = h; specifically the first line. No element in the dom could be found that has class logo1. In fact when I searched for class="logo1" there were no results in vs code. So I think somewhere a class name has been misspelled. Since these classes couldn't be found, can u guide me regarding where you intended to use these classes, logo1 and logo2.
