TracForge as fcgi in shared host
Fernando Garrido Vaz
Hi all,
I've been trying to setup TracForge in a shared webhost environment,
which means I can only run trac under cgi or fcgi. I have tried both,
searched the archives and tried what I found there (explicitly loading
all the modules in [components]), but the problem seems really to be
related to cgi. This is what I get when I run it under fcgi:

A problem occurred in a Python script. Here is the sequence of function
calls leading up to the error, in the order they occurred.

Under cgi, I get that message no matter what my trac.ini is, and no part
of trac works. And no, the file it complains about doesn't exist, you
will notice it is looking for directory "/hoe/......" rather than
"/home/....", so that will never exist....
Under fcgi, everything but the authentication works. I have changed
trac.ini back to what is suggested in the guide, here are the relevant
parts of it:

I have also tried enabling trac.web.auth.loginmodule, but surprisingly
(?) I get a message stating there is no handler registered for that
action when I access the login url.
Thnx a lot for your help.
