I use output buffering with the GZIP handler to compress my output.
I have always had it in the theme header/footer.
In 3.0, it has stopped working (sends junk to the browser).
That means that it is wrapped in ob_ calls.
At first glance, I can't find these calls. I ended up hacking the main index.php file to add these (YUCK).
Can anyone tell me where they added the ob_ calls?
