 * I upgraded last week and now get this message across the top of my site (ewanonline.
   net)
    Warning: ob_start(): output handler ‘ob_gzhandler’ cannot be used after‘
   URL-Rewriter’ in /home/.babbitt/kahnat/ewanonline.net/wp-includes/functions.php
   on line 459 I’m clueless and could use a hand or if someone could point me in
   the right direction it would be greatly appreciated. thanks kah

 * Typically, that error is due to running StatTraq while you blog is set to use
   gzip compression. The StatTraq developer is working on a fix.

 * Podz: no such link, it 404:s…
 * I have the same problem, it swamps my logs making it impossible to find any real
   problems.
 * Grateful for a solution. Had cpanel/fantastico uninstall WP and made a manual
   install of 1.5 to make sure it was not a cpanel/fantastico problem, but it sticks
   around.

 * _macmanx:_ Using your information I found an easy (temporary) solution, disabling
   gzip compression under Options/Reading. Now I do not get this error anymore (
   for at least five minutes… 😉
