    Warning: ob_start(): output
   handler ‘ob_gzhandler’ cannot be used after ‘URL-Rewriter’ in /home2/olympus/
   public_html/02/wp-includes/functions.php on line 452 Has this happened to anyone
   else in the past? Thanks, mat

 * i am still getting this after cleaning up some more of my index.php deleting 
   old calls…
    it appears to happen more often than not when loading the page for
   the first time just after the browser has been loaded… it also doesnt seem to
   matter what browser i use (Firefox, IE, Safari, etc) – As well as OS… Win XP 
   or OSX…. Does anyone have any ideas? PS. this Warning is at the very top of the
   index.php

 * Try Disabling the “WordPress should compress articles (gzip) if browsers ask 
   for them” option in Options->Reading. This happens because Apache already compresses
   the output due to your php.ini settings as used by your host.
    You can find out
   if the output is gzipped even after you turn the options off by using the service

 * I tried that and so far so good.
    Thanks so much. I looked at that URL you gave
   me, but it didnt tell me that information. Regardless, does GZIP do that much?
   What actually does it do for WP? Thanks again, mat

 * Hi all, I have also had this error in my web site. I did as you recommended and
   it worked. I guess that my server has enable mod_gzip, so I dont need tp config
   WordPress to do so.
