I upgraded from Fontawesome 3 to Fontawesome 5.Now I got several problems. If I am just linking the font-awesome.min.css in the head, the icons are not loading. I just see squares.If I link the all.css and tha all.js in the head, I works. So the icons are shown correctly. But everytime, I am clicking any Button and the page is realoding, it takes around half a second to reload the icons. In the previous Version it worked without the js and the icons weren't reloading at all.I am not sure why it is behaving like this. Maybe because all the <i ...> are converted into svg?
Do you have any hints what I can do?

The class names changed.
In FontAwesome 3:
<i class="icon-thumbs-up"></i>In FontAwesome 5:
<i class="fas fa-thumbs-up"></i>You should look them up here and change them manually.
