Issue with slider and need 404 page disabled


I am unable to get the slider working on my client site. It worked at some point but no longer does. I am unsure of what the issue is. Otherwise, if you can get the current image, garb2.jpg and garbage-heap.jpg working as the 3 images in the slider, that will be awesome!

In addition, I need the Mr.Fixer error 404 pages disabled. Please help!
