[Plugin: GPP Slideshow] Stopped Working

Hey I had this script on this site I made for punkmilk.com and I’ve been rung up by the boss today saying it’s down and been down all week. It use to run perfectly fine and I haven’t touched anything. I tried updating it to see if it will work and it still doesn’t, she wants it to be fixed today asap, please help
