Task 1 is no longer passing? Why?

The first two steps of this challenge work, but when I get to the third part, it says Task 1 is no longer passing, even though I haven't changed anything on the first line.

js/app.js 
let navigationLinks=document.getElementsByTagName('nav')[0].getElementsByTagName('a');
let galleryLinks=document.getElementById('gallery').getElementsByTagName('a');
let footerImages=document.getElementByClassName('social-icon');

Often you have to ignore when it tells you that "a previous task is no longer working". Sometimes a syntax error or other problem can break the whole thing, but it usually has to do with whatever line or block you were just working on.

Your first 2 are correct, so you can leave them. For the last one, you just need to change getElementByClassName to getElementsByClassName (plural) since it needs to return an array of multiple items.
