Internal Server Error

[Anna]

Hello,

 We've been using Eventum successfully for about a month now. We found it
very useful
in monitoring the issues and tracking bugs.

 Yesterday, we logged in to the system in the morning, but in the afternoon
it became
unavailable. We are getting 500 Internal Server Error:
_______________________________________

Internal Server Error

The server encountered an internal error or misconfiguration and was unable
to complete your request.

Please contact the server administrator, webmaster@stripped and inform
them of the time the error occurred,
and anything you might have done that may have caused the error.

 More information about this error may be available in the server error log.


  Additionally, a 404 Not Found error was encountered while trying to use an
ErrorDocument to handle the request.

We contacted our server administrator for help and received the following
reply:
__________________________________________

This error is being caused by an incompatible version of PHP for the site
you
are trying to run or a scripting issue in your site. This is the error that
I
am getting from the apache logs:

[root@host2 ~]# cat /usr/local/apache/logs/error_log | grep 69.16.222.113[Wed
May 7 21:18:54 2008] [error] [client 69.16.222.113] Premature end of script
headers: /home/cnmbeta/public_html/eventum/index.php

We'd very much appreciate if you could provide an advice, or any suggestions
on how this could be fixed.
