Aggregate and compress css files in Drupal disabled by default

[atari]

I would like to turn the Aggregate and compress css files feature on in my Drupal site, but it is disabled by default. I can't check the Enabled radio button because it is grayed out with the Disabled checked. Would anyone know why it is so in my case, and what am I missing, please?

Check your download method in Administer >> Settings >> File system

There are two possible settings for download method: Public and Private.

Set to Public if you don't care if any user, even anonymous users, can download the files uploaded by other users.

Set to Private if you wish to restrict the ability of some users to download files uploaded by other users.

If your method is set to Private, then the Aggregate and compress css files is disabled.

Note, just on the side, changing the download method from private to public once your web is running can become a major hassle, see this post: http://drupal.org/node/319334

Yeah, that is true. Never ever go from private to public. I tried yesterday, bad mistake. Always back up!!
