You should enter your FTP server information include username, password and hostname in handler.php file brdidge/php.

$oFtp = new FileManager(array(
    'hostname' => 'ftp.test.com',
    'username' => 'username',
    'password' => 'password',
    'passive' => true
));

Thanks for answering! :) I put my information in, and now it says "Error - 1 - Bridge response error, please check the API docs or this ajax response."
granted, I think I remember seeing that error yesterday before the FTP as well.
This comes from dist/angular-filemanager.min.js
I'll keep investigating. That said, I don't understand why I'm FTPing into my server without connecting to a database and table.

PS, are the instructions for setup actually sparse, or am I just uninitiated?

@dmh707 the bridges are more of an example. So you are supposed to implement your own. You can also check my php-local bridge if you want to work with local files.
