The last 2 is because you are probably using your admin account to view those files

Try creating a new admin account, logging in, and testing those files
The first one, I forgot, would cancel the action
Open admin/style.php
Find:
Code:
if ($action=="download") {
Add below:
Code:
if ($bbuserinfo[userid]!="1") {
echo"<p>You cannot perform this function</p>";
exit;
}
Should work
