OpenWRT 19.07.1: adblock problem

Hi,
I have two devices netgear WNDR4300 and BT Home Hub 5A both with latest version of openWRT 19.07.1.
I discovered that adblock plugin does not work. On both devices on the main page of adblock Runtime information are empty. Moreover, in the first device the log error is empty while in the second I get this error:

Fri Jan 31 09:20:09 2020 user.info adblock-3.8.15[11183]: your adblock config seems to be too old, please update your config with the '--force-maintainer' opkg option

I'm using for both devices the same configuration under Advanced->Edit Configuration:

I already tried to remove all custom filters.
Any idea?
