[wp-hackers] Where to insert mobile redirect code?

[Dion Hulse (dd32)]

If it doesn't work even there, this means you've got something
outputting data before they're loaded, which is bad.
Look at the source of a rendered page, and see if there's anything
output before the theme is output.

Also define WP_DEBUG to true, and see if any "headers already sent"
messages pop up, they'll tell you the line of code where the output is
starting.

Chances are, you've got 2 line breaks after a closing ?> somewhere.
