Good morning,
I am trying to follow the PHP tutorial, installed MAMP, and did the required changes, but when opening the localhost:8888 I get a message that says Loading.. but nothing else happens.

I tried different browsers, and I tried to use PHP version 7 and 5, but it is not working. Does anyone know how to fix this, or what settings am I missing?
Thanks
Fabio
