If you have any problem using RichFilemanager you may want to see what's happening.

All logs are stored at your local filesystem, so you have to configure your Local filesystem storage

To enable logger set logger.enabled option to true, also you can specify full path to logfile with logger.file option:

$config = [
    'logger' => [
        'enabled' => true,
        'file' => '/var/log/filemanager.log',
    ],
];
$local = new \RFM\Repository\Local\Storage($config);

Notice that, by default, logs are disabled and logfile location is defined by sys_get_temp_dir() PHP function:

• Linux: /tmp/filemanager.log
• Windows 7: C:\Users\%username%\AppData\Local\Temp\filemanager.log
