[Scott Murawski]

1)

Code: [Select]

File storage:
Select where you want to store uploaded documents. Warning: Switching storage will make all previuosly uploaded files unavailable.

previuosly => previously

2)

Code: [Select]

Autentify administration:
Sets whether a pasword autentification dialog is displayed when accsesing the administration panel

Autentify => Authorize (using Authorize probably makes the most sense)
pasword => password
autentification => authorization
accsesing => accessing

3) Also when setting the option to true, the main header should be updated to say "Authorize Password" or something similar.
