Corrects the following error :
scandir(/var/www/html/ice/lib/../backups/localhost): failed to open dir: No such file or directory in /var/www/html/ice/lib/settings-common.php on line 190
(possible review required for if this is something that should be created before this method is called, or if a simple check as this patch does is all that is required.)
globalized $context inside `GetVersionCount()` to eliminate `Notice: Undefined variable: context in /var/www/html/ice/lib/settings-common.php on line 203`
Added check if file is readable for `.version-index`'s inside the loop within `GetVersionCount()`
Using cookie_path on IE has an issue and causes session, then CSRF
issues
Stop using strict_mode as causes a problem on some setups
Add notes to these and httponly re IE and PHP version
No longer using session_start_safe() function because it caused more
usage problems than it solved. Setting a load of new params now to give
a much better setup.
Location shouldn't contain the dirname of the file or a loggedOut param
(with no CSRF!) - all unnecessary and causes problems
Also add a die() after the header location to go no further.
Some hosts have a loop around issue with no session being available
after a header location redirect
After much research, I've found this is due to some hosts not having a
session save path and it needs to be set using PHP
Setting this means ICEcoder works on those few hosts
Fix to bad URL on logout
