Edit
Defaults:
You can only save these
changes if you the default.txt is CHMOD 777. If
you chmod it 777, it will be a security risk of DOS from the web. (It is not a major
problem, because the only way they would be able to edit it would be in the admin area, so
it is relatively safe to chmod it unless you are afraid of someone guessing your password.
What is
this Default.txt:
The Default.txt file contains
the default settings for your topsites, each of these tags can be used inside of a <--top_tag
/top_tag-->, but if you don't define them in the toptag, these are the values
which will be used. This also contains some global settings such as the admin's email
address, and the path to sendmail.
