note: I am using WPMU 2.8.1, not vanilla wordpress!
I've just installed the W3 Total Cache plugin and it looks awesome... except, I can't select Amazon S3 or CloudFront for the CDN settings!
The option to do so is simply greyed (grayed?) out (disabled!) on the "General Settings" tab in the CDN section.
Am I missing something? The FAQ says to just select this option, but I can't!
As mentioned above, I'm using WPMU if that helps, and I do not have any other caching or S3 plugins enabled.
Thanks in advance,
