codeigniter cache returns always empty

You've saved it using

$this->cache->file->save('first', $data, 120);

Then get it using the right key and it should be first

$this->cache->get('first');

Also, to get information about cache you can use

var_dump($this->cache->cache_info());

Or you may use

var_dump($this->cache->get_metadata('first'));

This is useful for debugging.The get method accepts cache_item_id as parameter that you have used when you saved it

get(id['string'])

Problem solved, when I call the method to get the current cache I need to pass the used driver e.g.:

$this->cache->file->get('home');OR$this->cache->memcached->get('home');

Thanks.

Just create folder "cache" in "application" directory. It works for me
