I was having an issue with the mod blocking me, and when I checked the database I noticed it was storing 0 as my IP address. I traced it down to the file avh-visitor.php.
Where it says this:
if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4 | FILTER_FLAG_NO_PRIV_RANGE)) {
The $ip variable needs changed to just $i at this point, because it is within the
foreach ($ip as $i) {loop.
