"Administrator has blocked your account" message when I've got the only account

Summary

I was working on a new side project site and left if for a month. Coming back I went to login to /manager and got the message “Administrator has blocked your account”. I have the only account on the site.

I logged into PHP my admin and can see that indeed the account has been blocked.

How did this happen?

Step to reproduce

Attempt to login

Environment

MODX on LAMP server

That message is shown whenever your account gets blocked, not just when an admin blocks an account manually.

Most likely you (or an attacker if you have a predictable username) entered the wrong password too many times and the account was temporarily blocked as a precaution.

Yeah probably an attacker. I just left the user ‘admin’
