Problem with recent versions and apache2(?)

I see what you were getting at.  The complaint that is logged is:

[19-Jul-2006 22:43:59] PHP Warning:  Cannot modify header information  
- headers already sent in /var/www/apache2-default/roundcube_svn/ 
program/include/rcube_shared.inc on line 121

However, that isn't getting generated each time apache2 complains,  
which is pretty much on every action in roundcube.  Here's an apache2  
complaint:

[Thu Jul 20 11:41:56 2006] [error] [client 192.168.1.105] PHP  
Warning:  Cannot modify header information - headers already sent in  
Unknown on line 0

Real informative.  The relevant section in program/include/ 
rcube_shared.inc is:

    118      // include meta tag with charset
    119      if (!empty($this->charset))
    120        {
    121        header('Content-Type: text/html; charset='.$this- 
 >charset);
    122        $__page_header = '<meta http-equiv="content-type"  
content="text/html; charset='.$this->charset.'" />'."\n";
    123        }
    124

I don't know enough about what comes before this situation to  
diagnose, frankly.  I'm just putting it out there.

My theory is that the roundcube-logged complaints correspond to the  
blanking of the window, and perhaps have something to do with caching  
of different versions, because they seem to have gone away after  
using one version for a little while.  The copious apache2  
complaints?  I'll leave that to someone who has a clue about this code.

Thanks!
