Do not change the username or domain name for any of your domains

Please do not change the username or domain name of any of your domains. Thes function inside WHM, "Modify and Account" does not work correctly and it causes major problems for that domain and the server as a whole.
Please treat this very seriously.
If you need a username changed on a domain, that domain will need to be deleted, and then you can recreate it from your WHM.
The consequences of using this function range from your account backups not working, to completely corrupting the apache configuration file, which results in downtime for you, your clients and others websites
