When I choose to "Compose to selected", I get the following mesage: Warning: Cannot modify header information - headers already sent by (output started at /usr/share/squirrelmail/functions/page_header.php:31) in /usr/share/squirrelmail/src/addressbook.php on line 286 If I just click on a single address hyperlink, it works. Selecting one or more address with the checkboxes results in the above error, once the button is pushed. I am running Ubuntu 8.10 Server, with Squirrelmail 1.4.15 installed: cmauser@stagemail:~$ dpkg -l | grep squirrel ii squirrelmail 2:1.4.15-3ubuntu0.1 Webmail for ii squirrelmail-locales 1.4.13-20071220-1 Translations Is there a way to avoid this error? I'm trying to update the system using Ubuntu's commands, so I'm not sure if I want to manually upgrade Squirrelmail. ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ----- squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@xxxxxxxxxxxxxxxxxxxxx List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
