I have main domain (mydomain.com) and several subdomains (mysub.com, etc). When I create an FTP user, I can only create
user@mydomain.com. I vaguely remember that I was able to create
user@mysub.com as well. Am I making it up? And more important, is it possible in new CPanel?
I don't know if you're making it up or not, but at the current time it doesn't seem possible to make ftp accounts in a subdomain in cpanel. All FTP accounts have the @maindomain.com automatically added.
Also, is there a way in the new CPanel to edit home directory? Directory column has a fancy (scary, really) fisheye effect, but if I click on it - it works as hyperlink; not as "edit" link. Is the only solution to delete the user and recreate him?
Not at this time. The fish-eye thing is kind of goofy, to be honest, but it's what they decided to go with for the cpanel x3 theme. The only real solution is to delete and re-create any ftp users that you want to modify the home directory of.
