BP 1.7.2 BB 2.3.2 BPDocs 1.4.4 is not working

I have installed this plugin, created the page named “dokumenty” put shortcode [wp-publication-archive]. In the wp-config.php I I put define( 'BP_DOCS_SLUG', 'dokumenty' ); update permalinks… and nothing. Custom slug is not working.

Permisions still not working – pls see pic
I have created new doc, set permissions to read and comment logged-in users but “Comment posting has been disabled on this doc.”

And much more…
