Error message ‘ob_gzhandler’

Hello,

I just checked my error logs and I found that this error is repeated almost every few seconds:

Fri Sep 9 07:58:11 2005] [error] PHP Warning: ob_start(): output handler ‘ob_gzhandler’ cannot be used after ‘URL-Rewriter’ in /home/thebloke/public_html/wp-includes/functions.php on line 585

It might have something to do with the other problem I have been trying to deal with in the past few days, that is documented here.

Does anyone have any suggestions on how to resolve or troubleshoot?

Thanks!
