FTP Users on ISPConfig 3 again

[silverweb]

I want that a ftp login and the database name coincided with a client name.
But the panel does not allow it to make, tells the user name empty.
[CLIENTNAME] as the prefix costs.
In early versions ISPConfig 3 is worked.

Please post what you entered exactly in the prefix fields.

System-Interface Config
FTP user prefix - [CLIENTNAME]

[till]

You can not use whitespaces in username prefix.
