By the way, I have another Wordpress blog, and wanted to see those comments written by wp-cache... and I found the same error:
Couldn't write to: /home/.tonka/xxxxx/blog.manzanasfrescas.com/wp-content/cache/wp-cache-c1ab6f47775fe09cb35c3eec0d639b29.html

Reloading the page it worked properly... but those are not really nice error messages, and what about that "No space left on device in..."?
I suppose that's not the main issue, tho it looks it's at 100%
9.1T 9.1T 31G 100% /home/.tonka
Also I've not been able to see those wp-cache marks at my blog at blog.manzanasfrescas.com, where are 'em?
