BotBanish has encountered a situation where some legitimate users were being denied access because of heavy usage. This issue has been resolved and it is advised that you empty your botbanishclient_ip table in your database and remove all deny from xxx.xxx.xxx.xxx IP entries immediately after the following area in your .htaccess file:
<Limit GET POST>
order allow,deny
allow from all
</Limit>
Allow BotBanish to replenish the IP addresses. This process will remove any deny access to those user so that they can access your site again.
