Just had a look at the source code after reloading a page a few times and it seems that queries are still being called from the database rather than from the cache - or even being cached in the first place, as all of the .htaccess files under the tmp folder contain the following 2 lines:
Deny from all
I have enabled caching, but nothing seems to be happening. And no, I don't have any other cahching plugins installed, let alone active... :-/
Any ideas anyone?
Thanks in advance,
