Strange issue when trying to login.

I have 4 new WordPress sites that i have built, all the same setup with theme and plugins and all have been running fine with the free Wordfence installed.

Except the other day i tried to login to one and it said wrong login details, i was sure there were right but did a reset anyway. I still couldn’t login and the little eye preview for the password did not show the password when clicked. I changed the password in the DB to be sure but it still had the same error. I was not locked out even with quite a few attempts and the limit is 5. So i deactivated Wordfence and i could login fine with the same details. Its always work fine but i wonder if an updated has caused any issues?

I have also noticed that now one of the other sites is doing exactly the same and only works once i deactivate Wordfence by FTP client. So i have 2 working and 2 not and they are all exactly the same setup. Any thoughts of what to try to fix the issue? i did completely remove Wordfence from one site and then install it again but the issue is still there? its also the same if i use a different browser or incognito?

Thanks, Andy
