Questions

For example
I want it to say
www.google.com/emmy
Not www.google.com/index/emmy

How did you get it to have index/emmy?!? Don’t think I’ve ever had a bubble app be .xyz Domain Names | Join Generation XYZ, it’s always xyz.com for the index page then every other page is .xyz Domain Names | Join Generation XYZ

Didn’t even know you could go .xyz Domain Names | Join Generation XYZ
