Hi! Same error here. But I get locked out even myself. I removed your plugin to be able to enter my admin, this was the only option. I deactivated wps hide login, reactivated your plugin, same error. It’s crazy for a fews days now. If I hit logout from my account it locks me out. My clients as well.
I go to the message: If you are a WordPress user with administrative privileges on this site please enter your email in the box below and click “Send”. You will then receive an email that helps you regain access. I put my email there and I get another error: it redirects me to a 404 page with the message: no such page here. No email to unlock myself either.
Could you, maybe, fix it?
Thank you!
