Instiki users - Mar 2009 - [Instiki] upgr to 0.16.5, now get blank pages back except on localhost

Hi -- we had a working 0.13.x (I think) instiki install. Upgraded to
0.16.5 today (install in new directory, copy of database, run
upgrade_instiki script, edit config file with server name), and while
I can access it just fine from the server machine itself, from other
machines in the same network segment, I just get empty pages back --
not 404s or any errors, just no data in the pages it returns.

I''ve reverted back to the previous copy, but we have some serious
issues with the cacheing bugs in that and really need to get up to
0.16.5 ASAP!

Here is a log excerpt demonstrating what the server is doing with
those requests which result in black pages returned (in this case, the
requests are from client machine 192.168.254.42).

FYI, the server is set up in internal DNS as wiki.XXX.internal and
resolvable as such by clients on the network

Al thoughts gratefully appreciated!

If you can access your wiki from localhost, but not from another  
machine, that would seem to be an indication that the problem lies  
with your networking setup (firewall? proxy server? dns? ...?), rather  
than with Instiki.

This is exactly what a log entry for a successful cache-hit would look  
like.
And, I gather, if you accessed the same page from localhost, you would  
get a
nearly identical log entry, EXCEPT that you would actually be able to  
see the page.

Yeah you would think so -- but there''s nothing between the server and  
the client machine that would filter content -- and replacing he  
current version with the earlier install, it all works again (same  
server, same client, same network)! Any thoughts on anything else that  
I can trace to try and understand this?

   curl -D - http://wiki.XXX.internal:2500/wiki/show/HomePage | less

might offer some insights. As would trying other actions (new/ 
edit/...) instead of ''show''.
