phpmychat plugin complains "Cannot modify header information"

I have shell access to two machines with Geeklog v. 1.3.11, fc3, apache, mysql, and php installed. The plugin phpmychat installed successfully on both machines, but, it complaints with the "Cannot modify header information" on the second machine when accessing a chatroom (the full complaint is below). I have duplicated the working machine's entire public_html structure onto the complainting machine with no change.

Although the OS configuration and geeklog installation on both machines are identical in many ways there is obviously a difference between the two environments that I can not find. For instance, on the complaining machine, I had to modify the professional theme header as suggested in an earlier post by removing the first line in header.thtml to stop the same complaint for another plugin.

I have been troubleshooting this complaint for several days, in addition to performing several clean installs, and I am now clueless as to what I need to do next. The full complaint is below.

Update: Between the time I began writing this messages and just before posting, I found a discussion with the same complaint that recommends a change:

Text Formatted Code



I made the change in php.ini and restarted the httpd server and "poof" the complaints about the headers were gone! I am not really sure whether this change will backfire later.

Unfortunately, the complaint about PASSWORD remains.
