Thomas,

Thanks for the quick reply. For some reason I don't get it in my email. Only when I google the error again today, I saw your reply.

I'm using moin 1.8.2 on wk28. However, when I tried with 1.8.8 today, to create a simple demo wiki, I got the same error. I'm testing with Python 2.6.6.

I'll take a look at 1.9.3. Plan to have a simple demo wiki running, as a proof of concept, on w2k8. Then I'll upgrade my current 1.8.2 to 1.9.

Which moin version exactly?

1.8.8 is the current 1.8 release, but you maybe should rather try to use
1.9.x as the end of support for 1.8 is not too far in the future.

1.9.x is WSGI based, so WSGI is the preferred method to run it.
You can also do fastcgi, cgi, and others using flup (which is possible,
but not recommended).

2.6.latest is currently the most commonly used python, 2.5 should also
work ok. 2.7 is rather fresh and not much tested with moin 1.8.

These are NOT http headers obviously, but moin's log output (which is
usually either output to stderr (NOT stdout as the http headers) or to a
file - maybe check your logging configuration.

Looks like some error in the code, try with latest moin please.

I don't think this is caused by the different windows version, but
rather by a setup or configuration problem or a bug in moin's code (that
is maybe fixed since long in current moin versions).
