DB caching problem

[eluser]veledrom[/eluser]
Hi,

$this->db->cache_on(); creates folder called cont+meth

$this->db->cache_delete('cont', 'meth'); doesn't delete folder above.

$this->db->cache_delete_all(); removes everything from main cache folder including htaccess and index.php

database.php

Code:

$db['default']['cachedir'] = './application/cache';

config.php

Code:

$config['cache_path'] = '';

Can anyone tell me why $this->db->cache_delete('cont', 'meth'); doesn't work?

Thanks in advance
