So I created a simple dancer application in a single file:

    use Dancer;
    set logger => 'file';
    set log => 'core';
    get '/' => sub {
        debug 'allo';
        return 'bye';
    };
    dance;

Then I ran:

    curl localhost:3000

When I viewed logs/development.log, I saw the expected debug message.

Maybe it would help if you provided some code that can reproduces the
problem you are experiencing.  And tell us exactly which version of
Dancer you are running.

Thanks,
