cache backup adapter?

[eluser]riggerthegeek[/eluser]
I believe it to be a bug. I've got similar issues when I've tried using the Memcached caching driver, as my server hasn't got it.

The only thing I can suggest is to install APC (or Memcached). Simple enough on an Ubuntu server

Code:

sudo apt-get install php-apc php5-memcached

Personally, I find this driver a bit shonky for this very reason. I prefer to use the file-based caching.
