I would add
"Please note that, depending on your OS and configuration, files and folders with a '.' prefix may be hidden."
Or should we assume that the general user-base is aware of this (and thus remove the note in Logging aswell)?
[CG] Good hint, comment added.
In the "Database Directory" section, is the reference to a directory named "datda" a typo? Maybe it is supposed to say "data" but I'm not sure enough to change the actual page.
