ResponsiveFilemanager | The upload folder there isn't. Check your config.php file.

I want to use ResponsiveFilemanager plugin with tinyMCE. So I added requirement codes to init() function.

 external_filemanager_path: "/filemanager/",
 filemanager_title:"Galeri" ,
 external_plugins: { "filemanager" : "/filemanager/plugin.min.js"}

Then edited config file

'upload_dir' => '/uploads/',
'current_path' => '../../uploads/',
'thumbs_base_path' => '/thumbs/',

As I know this is enough for the display my images on file manager but it gives this warning..

There is an error! The upload folder there isn't. Check your config.php file.

How can I fix this ?
