Hello, I am struggling a bit trying to remove the 'Shop Account' feature and button. Can anyone help me out please? :P

I don't see why you want to disable this, this allows users to navigate their shop account page quickly. This only appears when you're installing WooCommerce.

In any case if you want to remove this, navigate to Dashboard > Forums > Settings > Styles admin page, put this CSS code in Custom CSS Code textarea, save it, delete all caches and do Ctrl+F5 on forum front:

#wpforo #wpforo-wrap #wpf-pp-shop-menu{
    display:none;
}
