I have a site where I have been adding a few IPs via the IPDeny manager in cPanel. The site uses cPanel v11.26.20_RELEASE_49708 adding the IPs has corrupted the .htaccess file. The IPDeny mgr has been adding the blocked IPs after the closing tag of the <Files 403.shtml>......</Files> block. This has caused the site to respond with error 500 for all html requests. I manage several sites and have only seen this problem at one site with this cPanel version. One thing different is that, within the cPanel IPDeny manager, it will accept an IP range of.. 18.104.22.168 - 22.214.171.124 whereas all other versions choke because of the spaces each side of the dash. Others seem to only accept 126.96.36.199-188.8.131.52 I usually use CIDR range settings, but not always. has anyone else seen this problem of cPanel messing up .htaccess? biterg.
