    This message is returned when you try to enter an invalid character in the username field.

    Can you connect to your site over FTP, and check if this file exists: wp-content/nfwlog/cache/bf_conf.php. If it does, delete it and try again.

    You can check for JS error by opening your browser’s JS console (usually CTRL + Shift + J).

    @nintechnet Thank you for your reply.

    After a lot of looking around and carefully reading your instructions, I decided to copy bf_conf.php from one of the working websites to all of those that don’t work.

    This fixed the problem!

    I have reset the Login Protection settings with new usernames and passwords for each of those websites, and everything works well now.

    Looking over the usernames and passwords, I believe that I know what caused the problem.

    On the sites that weren’t working, I had chosen a username with a space in it. I see that your system no longer accepts a space, but once upon a time it did, and so those usernames now caused a problem.

    Thanks for your help!
