in reply to New Plack App (with HTML::Template & file upload) help

You could help us help you better by posting the relevant part of your code. Most likely, you have in your request handler something like:

sub handle_request {
    ...
    my $html = '<html><head>...</html>';
    ...
    return [ 200, ['Content-Type','text/html'], $html]
};

But that is not how the PSGI protocol works. It wants you to return an array reference:

sub handle_request {
    ...
    my $html = '<html><head>...</html>';
    ...
    return [ 200, ['Content-Type','text/html'], [$html]]
};
