Hello, Recently I've setup a new centos 6.2 64 bit server and upgraded to 6.3 via the yum repositories, and installed/setup plesk to work on a setup for a client. No changes or recompilations have been done to the system, besides the default update tasks plesk does. I did create a client owner account to add subscriptions to it. All subscriptions made for the domains are using the unlimited package with unlimited amounts of domain aliases, and the subscription has the domain alias manager enabled as well After going in, creating a few domains and using FTP to upload files to the httpdocs folders, I went to add some domain aliases as the client requested. In adding the domain alias name of "kids" I get the following error: Error: The domain name you specified is invalid. Domain names can comprise letters, digits and hyphens. Each part of the domain name between dots should not be longer than 63 symbols. This is a clean install so I'm seeking any suggestions on how to get around this or correct the issue with not being able to add domain aliases. Anyone have any suggestions on things to check or how to fix this issue?
