I get this message at the top of my page, when I refresh it goes away, but I'd like to know what it is and how to fix it. I thought at first it might have something to do with the SEO plugin but after disabling it I still get that message.
Warning: ob_start() [ref.outcontrol]: output handler 'ob_gzhandler' cannot be used after 'URL-Rewriter' in /home/xxxxxx/public_html/frontpage/wp-includes/functions.php on line 408
if I click on [ref.outcontrol]I get this;
file not found
ETA: Just came across HandySolo's recommend to disable gzip, will try that.
