I have other sites using Wordfence on this same server that don't show entries like this. And I have 20+ sites I maintain that use Wordfence, and have not seen similar logout entries on any of those.
No caching is set up on the site yet, and haven't set up any cron jobs, so it's not that.
There are 23 new entries like this from a French IP address now.
Wordfence developer(s): Any ideas as to why this happens?
