CI3 - place index not in top directory [SOLVED]

Hey there. I've got a couple different places I put my CI3 website. One of them (a version I use for testing) is at http://localhost/Folder1/Folder2/Folder3/. Having all those folders between localhost and the index.php file is confusing CodeIgniter and is resulting in it detecting the class as Folder1 and the method as Folder2.

So for example http://localhost/Folder1/Folder2/Folder3/class/method should be [class=class, method=method], not [class=Folder1, method=Folder2]

Is there a way to fix this without changing my directory structure? Help much appreciated.

What's your base URL?
