I can't answer your question, but it might help if you can post a backtrace. You can refer to the following thread for an example of how to do this:

Hello,
I just upgraded from 4.2.3 to 4.3.18, and we are getting errors when acknowledging alerts. I saw other people wrote to the list with similar problems, but I didn't really see a solution (or I just missed it.) So I apologize in advance for the duplicate question. Any help would be appreciated.
This is the error we see in the web interface:
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, xxxx at xxx.xxx 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
This is in the Apache error log:
[Fri Jun 19 14:37:16 2015] [error] [client xxx.xxx.xxx.xxx] Premature end of script headers: acknowledge.sh, referer: https://hobbit-test.syr.edu/xymon-ackcgi/acknowledge.sh
The messages file indicates it is creating a core file:

Since we want a certain group of people to be able to acknowledge alerts, I copied the acknowledge.sh script/link to another cgi directory:
[root at hobbit-test xymon-current]# ls -al cgi-ack total 208 drwxr-xr-x 2 xymon xymon 4096 Jun 19 13:32 . drwxr-xr-x 8 xymon xymon 4096 Mar 5 10:28 .. lrwxrwxrwx 1 xymon xymon 49 Jun 19 13:32 acknowledge.sh -> /usr/local/xymon/xymon-current/server/bin/cgiwrap
This is a portion of the httpd.conf file:
ScriptAlias /xymon-ackcgi/ "/usr/local/xymon/xymon-current/cgi-ack/" <Directory "/usr/local/xymon/xymon-current/cgi-ack"> AllowOverride None Options ExecCGI FollowSymLinks Includes Order allow,deny Allow from all
Require group ackers</Directory>
