I've had enough support tickets with Cpanel's addon domain system. It is neccessary to create a subdomain? the current system needs a revamp in my opinion. There is absolutely no error checking with the add-on script. Cpanel developers can you please make changes to the add-on domain as it sucks like hell. I also swear that I get more support tickets regarding Cpanel malfunctioning or something than actual support issues related to anything else. I'm comparing two servers of mine, one with cpanel and one without. And also 8.5.3-s3 is not stable.
