WP 2.9.2, W3TC dev. from 24 June, Cloudfront CDN, Minify.
OSX Safari users (old and new versions) have reported that the site is displayed without CSS. After confirming the problem, I disabled Minify and emptied the cache, but still Safari discards the CSS.
Tomorrow I will update W3TC to the latest dev. version, but I will not have immediate access to an OSX box for testing. Has this issue appeared before? What can the cause be?
The site is http://www.nazioneindiana.com
According to this thread there could be an issue of server PHP configuration for max_execution time or memory limit, but the correlation to Safari seems weak there.
