new production install - Nav-users

1 Nov 2007

      After installing nav in the test enviorment on opensuse 10.2, I
installed nav on a new virtual production system with opensuse 10.3.
BTW the python version is the same.
Nav is starting without errors, but in the toolbox Alert Profiles is empty.
And Status give the following error page:

What do you mean by empty? Is the descriptive text missing, or the
icon?

Yes.  The same problem was discussed on this list in May.  See
http://desperados.itea.ntnu.no/pipermail/nav-users/2007-May/001635.html .
Basically this error comes up on newer versions of mod_python.
Your options are:
* Upgrade to NAV 3.3 (I don't think anyone has made an RPM of this
    version yet, though.  Mr. Krapivin has been strangely silent)
* Or apply this patch:
    http://desperados.itea.ntnu.no/pipermail/nav-users/2007-May/001639.html

Begin with the lasr, install the patch.
That doesn't work, still the error page with status. When I comment out
the next two lines in
/usr/lib/python2.5/site-packages/mod_python/importer.py
       # Check for an attempt by the module to import
       # itself.

=>     # if parent_info:
=>     #     assert(file != parent_info.file), "Import cycle in %s." % file

Status seems to be working.

The toolbox/alert profiles page is complete empty, only a white page is
displaying.

Anmd I use the source  nav-3.3.0.tar.gz
