FashStore widget problem

All of the widgets in my homepage suddenly disappeared when i tried to remove text-decoration with JS code.

let all_defected_items = document.getElementsByTagName("a");
for(let j = 0 ; j < all_defected_items.length; j++){
  all_defected_items[j].style.textDecoration = " none ";
}

It didn’t work so i removed the code and when i refreshed the site all of the widgets were gone . They are visible in the admin panel , i can rearrange them and edit them nor they are disabled but still they are not visible to the user .
What i have tried by now:
-Clear the cache of the site
-Toggle on/off/on all plugins
-Reinstalled couple of them

The page I need help with: [log in to see the link]
