Hi @nziakas78
Thank you for the update.
That block page and block reason is for when someone tries to login with a banned username under the option Immediately block the IP of users who try to sign in as these usernames.
It’s possible that you haven’t configured Wordfence to detect IP addresses correctly and Wordfence is seeing hackers and everyone else, including you, as coming from the same IP address. If a hacker generated that block page then everyone else will see that block page until the block expires or until a proxy IP address possibly changes.
Once you have regained access I would like to have a look at your Wordfence diagnostics report so that I can check the IP detection for you. Please go to the top of the “Diagnostics” tab on the Wordfence “Tools” page. There will be a “SEND REPORT BY EMAIL” button to send the diagnostics report. Enter wftest [at] wordfence [dot] com as the email and nziakas78 as the forum username please.
Once you have emailed me the diagnostics report can you reply here to let me know that it has been sent. This is important in the unlikely event that your installation of WordPress is having an issue with sending mail.
