Script Error- Upfront Won't Allow Me to Access my Home Page

Hi,

I keep going to edit my home page using upfront, but it stops loading around 39% and then says that there is a script error. I’ve cleared my cache on my browser, as well as the upfront cache, and I even went to my hosting site and tried to clean “plugin leftovers” in the phpMyAdmin database. I’m not sure what else to do and I just want to edit the homepage! haha I have granted access to the site. Let me know, thank you!
