Problem with adding banned ip addresses.

I can't get a banned ip address to be saved. I enter the number and submit but it just doesn't stick. Any idea what could cause this problem and what would the fix be? I am using Advanced Guestbook 2.3.1

Also, some ip addresses are not indicated by numbers but look something like this: c-67-163-xxx-1x3.client.comcast.net -- Can this type of address be listed?
thanks

Find the thread on Advanced Guestbook Fixes and Mods - somewhere on page 1 of the topics. In it look for a link to a topic something like "Quick mod to log IP instead of host name" Install that mod.

I don't know why you can't ban IPs. Are all your permissions set correctly according to the readme.txt file? Are you using the right number of digits for the IP?

Banned IP's are stored in SQL so file permissions would make no difference. Are you putting them on different lines?
