  • Resolved blau


    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

    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.

  • Upgraded to latest dev version today, the problem is not solved. Safari displays a CSSless site, other browsers are ok.

    Tried disabling Minify, db caching, object caching, with no visible results.

    I see that you have 6 different css files, all of which were .gz compressed. Let’s look at the first one:
    <link rel="stylesheet" type="text/css" href="" />

    You are have the attribute type=”text/css” but sending it a .gz file. They are not the same. I believe the correct mime-type is “application/x-gzip”. You might want to do a google search on this, but the server may also be sending incorrect header information.

    The rest of the css files have id’s in their links. I’m not sure if that is appropriate either.

    I hope this helps.

    Please try the latest development version of the plugin.

    Hi, sorry for being this late, but real life prevented me to work on this issue so far.

    Turns out Safari browser does not understand .gz extensions, but the issue is solved in the development version of the plugin which gives an .gzip extension to the css. Updated, tested, ok.

    Thank you Frederick for your great work.

    That is already addressed in the development version of the plugin.
