Today I want to add a DB-User and DB. Since today the username was created with a prefix like c12_myChoosenName. But since today the Prefix is gone, and I don't know why. On System ⇒ Settings ⇒ Site ⇒ DB Userprefix the Textfields where empty. I try something like: c[client_id]_ or [SERVERNAME], but they wont be replaced if I create a new DB-User. Any hint, why this not work... and which Placeholder to use here?
