Hi @mbwd, sorry to see you’ve had a couple of issues around this.
Under normal operation, the locking out of invalid usernames checkbox only affects usernames that are attempted but also don’t exist in your database. Live Traffic will show the cause at the timestamp you were blocked in red text when expanding the line by clicking it (or using the “eye” icon), just to be certain that another Brute Force or Rate Limiting rule wasn’t being kicked into action instead. Let me know what you see there.
With logging out and being locked out, it seems like something about that process is being flagged as a false-positive so you could try enabling Learning Mode and trying again to teach the site it’s a normal operation. Again, if that doesn’t work, Live Traffic should give the reason as to why the logout at that timestamp was locked out.
I have a nagging feeling that IP detection might also need to be checked as you’ve explained experiencing the same problems with other sites. There does sound like the possibility of blocks for other users/bots effectively applying to you (and everybody else) when they shouldn’t. Check your own public IP address first: https://www.whatsmyip.org.
Head over to Wordfence > All Options > General Wordfence Options > How does Wordfence get IPs and reference the area under that section that says Detected IPs and Your IP with this setting. See if any of the options there when picked accurately reflect your IP. If another one does rather than your current choice, don’t forget to hit the SAVE CHANGES button in the top-right after you’re done.
If you see anything in Live Traffic that you’re not sure how to rectify, or the cause continues to point to the original invalid usernames setting, by all means let me know so we could possibly look into it a little further.
Thanks,
Peter.
