Purging feature should also delete old log entries

As stated in title…
Set duration to 1 week, message ‚Purging entries older than 1 weeks‘ appears once a day but older entries are not deleted.

The purging option is only about purging failed logins, old banned IP entries, and old unblock entries (in the database).
What you show is the log file ([joomla-log-directory]/plg_system_bfstop.log.php) - there currently isn't an automatic way in bfstop to delete or trim the log file.

Two workarounds would be

1. If you have shell access to your server, create a log rotation configuration for the bfstop log file
2. Occasionally delete the log file, e.g. via FTP/SFTP.

It sounds like a good idea however, to have an automatic mechanism in place for trimming the log file, in order to avoid overly large log files clogging up disk space on the server. I think even Joomla itself does not provide any support for deleting/trimming its log file at the moment (though I'm not 100% sure on that).
