Revolution Slider Not Showing Up Anywhere

Hi. I’ve been using Revolution Slider for some time now and it has always worked perfectly. However, recently (within the last few days) it’s decided it doesn’t want to work anymore. It’s not showing up on desktop, tablet, or mobile. For the time being I’ve switched to Layer Slider which is working just fine but I would like to switch back to Revolution Slider. Any help would be greatly appreciated.
