I have 85% disk space available:
and this is the permission in config.php file:
$CFG->directorypermissions = 0770;
[Changed it to 0777 as well but no luck].
Kindly suggest a solution to this. Thank you.

Re: Unable to save the cache config to file. Please help!
ó $a->name - $a->date
Try deleting cache and local cache from your moodledata (not moodle) folder. Check permissions on that folder too.
