headers already sent in ... rcube_shared.inc on line 143 ..

The following is constantly being spewed into apache's error_log:

[Tue Jan 09 15:20:30 2007] [error] [client 10.10.10.10] PHP Warning: Cannot modify header information - headers already sent in Unknown on line 0, referer: ​https://intra/rcm/

This looks similar to #1483926 but even with that applied this happens, just less ;) This is with Apache 2.2.3, PHP 5.2.0, MySQL 5.0.27 on Centos 4.4.

HTH. I'll gladly provide more information if necessary.

I concur...this needs to be investigated more thoroughly. I get a lot of the exact same "Cannot modify header information" messages in my apache error_log. My setup is Apache 2.2.4, PHP 5.2.0, MySQL 5.0.33 on FreeBSD 6.2-RELEASE.

Looking forward to a solution. Apologies for not being expert enough to find/fix the bug myself.

Maybe this ticket should be closed. It's the same as #1483926.

I know that the problem is in the function rcube_iframe_response() in the file /program/include/main.inc. This function is recalled from the files upload.inc and sendmail.inc in the /program/steps/sendmail.inc. I think that the problem resides in the sendmail.inc.
This week I will investigate to fix it.

I've resolved this problem deleting the line 1980 in /program/lib/imap.inc.

Test it and then close the ticket if it works.
