Hi,
I'm having a litle issue in my DW installation, I'm getting this messages
in the apache error_log:

PHP Warning: Cannot modify header information - headers already sent in Unknown on line 0

I was thinking that the problem was my template, but using the default template I still
see the error.

How can I debug this kind of errors in DW or in php ?
The server is running CentOS 4.4 with official updates

Thanks
Oliver
