Checked recently added albums, and if played the album art is displayed OK.

As far as I can tell that's not the thumbnail generation, but the library itself, that gets sent to the UI. And everything looks ok (0-byte files for not-yet-applied library filters are expected behavior).

Thumbnails, OTOH, get (re)generated by the relevant command in the LIBRARY configuration tab, or automatically (the missing new ones) upon a library update under the "m" menu.
Such thumbnails are stored in the /var/local/www/imagesw/thmcache folder. They have weird names (the hash of the folder the relevant music file is in...) but that's the way the UI expects them to work.

Now, since we're here also to try to help, can you tell us what is that makes you assert the thumb-generation fails?
