logs location & task

[cbob]

Hi,

I would like to ask:

1) can I change logs storage location (uploads/logs/) ?

2) I would like to use system cron.  I have setted /applications/core/interface/task/task.php chmod 0777, but still have got message "In order to enable this setting you must make the ***/applications/core/interface/task/task.php file executable (i.e. chmod 0777)." and cron is not set..
