Problem with image upload

Hello!

I`ve copied modx project from one server to another server.
And now i have problem with FCKeditor.
When i want to upload or create folder in FCKeditor, that says I don`t have permissions.
I set permission 777 to all /assets/ and /manager/ folder, but nothing happens.

Maybe someone can tell me where i can found config for path where images and folder will create?

Thanks.
