Migrating nagios to new server

[Alex Farrer]

I'm having a minor problem migrating my Nagios 1.2 installation onto a new 
server. Since this new machine is running the same OS (Fedora) rather than 
recompile and install nagios from scratch, ive simply copied the entire 
nagios directory from the original server to the new server. I've made sure 
that all the libraries are installed on the new machine (using the same 
rpms), the directory structure is exactly the same, permissions are right 
and the webserver is set up the same. So I start up nagios, and everything 
runs fine, with no error messages.

However, when using the web interface, each of the cgis that should appear 
in the right hand frame on the screen display a "Error- Msissing 
Content-Type" header?

Any ideas where i'm going wrong? Ive seen a faq suggesting that i need to 
recompile without debugging enabled, but surely this doesn't apply in this 
case, since im using cgis that have already been compiled and work on an 
identical system?

Any advice or suggestions will be greatly appreciated!
