Hi! I am being told to enter an IP address or username, but when I do and enter the block settings I am told "There are problems with some of your input." ̶ "Invalid IP address"... But I am not trying to enter an IP addresses, only usernames. I don't understand!
Invalid IP address
There should be no extra spaces after usernames or IP addresses, otherwise they will be rendered as erroneous.
Nevermind! I figured it out! My entries all have two extra, empty spaces after them. I deleted all of the extra spaces and then it worked great! This will help me tremendously!
