CI4 in localhost

I'm afraid you are not. Check with phpinfo(), it's not enabled. Or you wouldn't get that error message.

No, you need a real virtual host to set it up.

Its' true , in my notebook there are several php , in use on localhost is the 7.2 , now work fine , thanks.

Now where is the correct url ?

the ci message are at http://localhost/ci4/public/ f.e. if i want run user/login  i try http://localhost/ci4/public/user/login

but i  have this error

Not Found

The requested URL was not found on this server.

*edit find must insert index.php as http://localhost/ci4/public/index.php/user/login
