Hi,
When serving the contents frame, the following error is generated:

The page served is missing the closing body and html tags, ending with:
<LI><A HREF="/cgi-bin/doc-central/browse.cgi?section=Text">Text</A>
<LI><A HREF="/cgi-bin/doc-central/browse.cgi?section=Viewers">Viewers</A>
</UL>
I'm sorry that I don't have the Python experience or time to debug this
myself at the moment.
When I try to use the search box at the top of the contents frame, I get
this error:
2026/02/12 16:07:41 [info] 116113#116113: *20511 client sent invalid request
while reading client request line, client: 192.168.10.54, server: , request:
"GET /cgi-bin/doc-central/%s?keyword=foo HTTP/1.1"
I don't know whether this is related or possibly due to a bad CGI
configuration on the server.
Thanks,
Roger
