I'm currently using WordPress 2.1. Just recently, I've begun to get the following error at the top of my site:
Warning: ob_start() [ref.outcontrol]: output handler 'ob_gzhandler' cannot be used after 'URL-Rewriter' in /usr/home/logan/public_html/blog/wp-includes/functions.php on line 336
Interestingly, this error only appears every so often, usually upon an initial visit to my site. If the page is refreshed, however, the error disappears. I can't think of anything I may have done (plugins installed, etc.) to cause this error to appear, since it has never shown up before. Any ideas on how to get rid of it?
