 * Hello! 🙂
 * I have installed W3 Total Cache on my site and since then some Chrome users have
   been reporting this error: 330 ERR CONTENT DECODING FAILED Most of them said 
   a quick F5 solves the problem.
 * I did some Google search and apparently this happens because W3 says “yes” to
   gzip and my website says “no”.
 * I found this website [http://www.gidnetwork.com/tools/gzip-test.php](http://www.gidnetwork.com/tools/gzip-test.php)
   and it says gzip is activated.
 * > Web page compressed? Yes
   >  Compression type? gzip Size, Markup (bytes) 28,372
   > Size, Compressed (bytes) 7,511 Compression % 73.5
   > Response Headers
   >  status HTTP/1.1 200 OK date Sun, 28 Apr 2013 02:52:54 GMT
   > server Apache vary Accept-Encoding last-modified Thu, 01 Jan 1970 00:00:00 
   > GMT content-encoding gzip content-length 7511 connection close content-type
   > text/html
 * But sometimes, if I keep pressing “check”, it also says, “Sorry, I am unable 
   to decompress the contents of this page. Possible bogus gzip/deflate encoded 
   data.”
 * Google Adsense is also displaying a warning telling me to activate gzip. I’m 
   lost! x(
 * I checked wp-admin/options.php and gzipcompression value is set to 1.
 * I’m very noob when it comes to such things, so maybe I’m missing something obvious?
 * Could you guys please help me out? Thanks!
