Renamed var to distinguish from ftpSite, which is checked for existance
with isset and if available jumps into FTP mode. Having it previously
set to false, it's available, so erroneously goes into FTP mode with no
creds. This is a standalone var name now just to establish connection
channel.
The 2 x if conditions added a security measure to avoid path traversals,
should languageBase or languageUser ever be set to something malicious
such as (eg ../../../../../../../etc/passwd)
However, it meant that the ICEcoder dir and the doc root dir paths had
to both start the same, and so be in the same location really. It was
previously a benefit to have them possibly contain different paths, but
this security point restricts this.
We can remove these 2 if conditions however and simply wrap the 2 array
values with basename(), so we take only the trailing file name and so
avoid path traversal issues.
Causes file locking issues if allowed to be called from anywhere
Because we only call from index.php now, also need dirname(___FILE___)
to complete paths
configCreateDate set if 0 now on every load, not just save
14 full days setup (1296000 - 1 sec), so doesn't start by showing 13
days (and 23 hrs, 59 secs)
If configCreateDate == 0, $tRemaining is the $tPeriod
If there has been a change of language, set a bool flag for a reload
later
Save languageUser to file also on settings update
realpath checking on language file name also, dies if fails
We should indeed only output if index.php and top.iceRoot is updated
after a settings change in settings-update.php (top.docRoot only changes
if you manually change the file, in which case a reload is needed and
this is picked up again from scratch).
