Public uploader widget

Hi everyone!

I recently installed this exceptional plugin, but theres a thing, i cannot upload photos from the public upload widget, when i press it just reload the page and not even show the success test, the same if i press upload without selecting a file, but when i upalod photos from a post with the [ngg_uploader] it does work! but i want to upload from the widget, can you guys please help me?

Thanks
