Touch Controls Suddenly Stop Registering?

I'm am through version 17 of an app I am working on. However, when the user (or I on Unity Remote) presses on a button, it doesn't register it. It has been working until now for some reason. When I actualy use my mouse to click a button in the game view it works, but not touch input.

*The buttons are located in a Canvas

*There is a sole event system

*There is a GraphicRaycaster

I don't understand what could be going on. I think it has something to do with the EventSystem but I've even added a fresh one and got rid of the other with no results. I'd also like to add that it does see touch events but it must not registering that a button is clicked. Any help will be greatly appreciated.
