Quoting Emeric Jhelil <emeric.jhe...@univ-lemans.fr>:
Hi,
I am using horde-webmail-1.2.2 with dimp-1.1.1.
I meet these kind of errors in my apache logs (they appear by two).
- after login choosing dimp :
[Fri Apr 03 17:52:46 2009] [error] PHP Warning: Cannot modify header
information - headers already sent in Unknown on line 0, referer:
http://test/imp/login.php
[Fri Apr 03 17:52:46 2009] [error] PHP Warning: Cannot modify header
information - headers already sent in Unknown on line 0, referer:
http://test/imp/login.php
- in dimp, selecting options or compose
[Fri Apr 03 17:52:54 2009] [error] PHP Warning: Cannot modify header
information - headers already sent in Unknown on line 0, referer:
http://test/dimp/
[Fri Apr 03 17:52:54 2009] [error] PHP Warning: Cannot modify header
information - headers already sent in Unknown on line 0, referer:
http://test/dimp/
I have selected in my horde/config/conf.php : $conf['compress_pages'] =
true;
And they disappear if it is set to false.
It seems to be linked to the flush function used in
horde/dimp/lib/DIMP.php (header function) .
The errors don't occur if compress_pages is set to true and the flush is
commented out.
Firebug shows these differences in the "GET dimp" http response header :
1) with flush and compress_pages = true :
Vary: Accept-Language
Transfer-Encoding: chunked
2) without flush and compress_pages = true :
Vary: Accept-Language,Accept-Encoding
Content-Encoding: gzip
Content-Length: 5155
Can it be resolved by a better configuration of my webmail ?
Are these missing header informations harmless ?
Is it better to comment out the flush function in
horde/dimp/lib/DIMP.php or to let these warnings occur ?
Generally this means you have an extra space in a config file
somewhere (not in a PHP code block).

Thanks for the quick reply, but I am not sure that my problem comes from
an extra space in a config file.
If there is, I have probably not introduced it so I don't know where to
search.
I have re-tested from scratch :
horde-webmail-1.2.2 (with original dimp-1.1)
drop database ; create database
php horde/scripts/setup.php to generate the basic conf (step 1, 2 and 3)
conf servers.php as minimal as I can (don't see any extra space in string ?)
The result is the same :
if compress_pages = true (it is after using setup.php script), my very
first log in produces the warnings in apache log but no peculiar
information in horde.log
if compress_pages = false, no problem
if compress_pages = true and flush is commented out, "no problem"
(compress_pages has been modified by the admin interface)
There is no pb in Imp, just Dimp...
Best regards
Emeric
