Warning: ob_start(): output handler ‘ob_gzhandler’

I had been getting the same error, it appears to be a PHP problem. you’ll have to disable the option in WordPress to send the browser a gzipped copy of the page(s) if requested.

I’ve started getting this error recently and I was using gzip for months. All of a sudden it’s having issues? I don’t get it.

Disabling gzip worked, but how come it started to freak out?

Using php 5.2? It changes how output buffers are handled during shutdown.
