I cloned bubble.is and the changes I made was playing with facebook login and changed the user logged in option.
When user is logged in. It was going to https://MYAPP.bubbleapps.io/version-test/home?debug_mode=true
I changed it to https://MYAPP.bubbleapps.io/version-test/index?debug_mode=true
Now site is not loading. It works fine on my cell phone.
