New Install

I just downloaded the latest stable Xymon release (4.3.21 and configured
and maked it but when I click on the items I just get a file to download or
a blank screen with a No Such Host message.  I looked in the server/cgi-bin
directory and there are a load of files ending in .sh but they are binaries
not scripts and all of an identical size.  I checked in the same directory
of a previous version and they are small shell scripts.  Can anyone help?

Regards,
