Devel 'Display Query Log' not showing any queries I've enabled 'Display Query Log' in the Devel Settings but I don't see any logged at the bottom of my page when I load a page. I just get 'Queries exceeding 5 ms are highlighted.'.

I'm running Drupal on PHP 5.3.2 with a mySQL database.

The issue is present in both the Admin theme and my custom theme.

Other Devel outputs seem to display fine.

Any ideas why the queries aren't showing?
You need to check 'Collect query info' in the devel settings: /admin/settings/devel 

Otherwise no logs can be shown.
