I am also seeing this problem. I have checked several things:
- wp_cron is working (scheduled posts are working, I can see wp-cron.php accesses in the server logs, etc.)
- The
redirection_options
are being stored in the database with the correct settings.
- The
redirection_log_delete
action does dhow up in the database’s cron option.
So it seems that all the pieces are there, but the logs keep growing. I have it set to get rid of redirection logs weekly and 404 logs daily. It’s definitely not working.
