[rt-users] RT failure following Fedora updates

[Bill Davis]

Running RT 3.6.5 on a Fedora Core 6 server (mod_perl), which has been 
working fine for months.  Rebooted the server, which identified several 
updates needing install:

Performed the listed updates, rebooted, and now find that I'm unable to 
access RT, entering the normal URL gives just an empty blank page. 

The other application hosted on this server (bugzilla) is working 
normally and can be accessed remotely.

Could really use some pointers as to what might have gone wrong, or 
where to look for a solution.

Thanks for any help ...
