After upgrading from Discourse 2.3.0 beta 5 to beta 6 I now have 14 new notifications in the new /review page, all regarding users that need to be approved.
Those users are either user accounts we rejected weeks ago or banned users, though.
If I clikc on the “Reject” button I get an error message “Sorry, an error has occurred” (see picture below).
TLDR version, I have 14 notifications about already rejected/banned users and I cannot find a way to get rid of them
