UPDATE: The Ads in the hans  site had the following MySQL error:

Unknown column 'bx_ads_reviews.cmt_pinned' in 'order clause'

This error is typical when the core of UNA has been updated and modules inside - not. As the upgrade attempt of Ads has met the error about too many modified files (8%) I applied the solution form this manual https://github.com/unaio/una/wiki/Upgrade , raised the available percent, completed the upgrade of Ads and the error has gone away.
