Unable to access Login Protection. Error message “Invalid character.”

    I host a few local charity and community websites. With one exception, they all don’t display the “Login Protection” at the back-end properly.

    Only the “Enable brute force attack protection” option is displayed, with “Save Login Protection” and the advert for benchmark and stress test.

    Upon clicking anywhere on the page, an error message pops up:
    “Invalid character.”

    See the sample screenshot.

    WordPress, themes and plugins are all fully up-to-date.

    I have no clue how to even begin to diagnose and solve this. Are you able to help, please?

    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!
