HelloI have had a similar problem. I keep coming to the site and having to reset my password. I generate a new password, and when I paste it in, I get the "Please correctly fill out all fields" message.
Today, when I ran into this problem, I think I accidentally fixed it. I inadvertently hit a backspace, and the red icon at the end of the password field turned green. I then deleted the last character of the verification field to match, and it turned green as well. I submitted again, and this time it took it *and* it allowed me to subsequently log in. I went into the password manager and deleted the last character. Why did this fix it? I haven't a clue, but I hope it stays fixed, and that maybe my accidental workaround gives someone a hint about what could be going on.
Browser is Firefox on Linux, and I *am* using a password manager.
Thank you very much for sharing. I tried your approach but unfortunately I still keep getting the same error? I sent an email to Admin with a screenshot.
