Ban Ip list hack

[kingtech]

I created a mod to add an IP to the banip value in the settings table .. if i add info to the value hack directly into the DB or with my hack it does not show IP as banned when you access the forum. But if i go into the admin > setting options and pull up the banned options .. I can see the data I entered .. save changes without changing the value and it works to ban the IP.. am I missing something ??

THanks !!!
