I can say for sure that something is wrong.
I've checked and doublechecked this and there is nothing wrong with
the lighttpd config, rtorrent config or the rtgui config. It works
fine with apache, but does not work with lighttpd.
This is with debian lenny AND squeeze. I also tried compiling a fresh
lighttpd manually from source. There is something which is causing
rtgui to not work.....my guess would be something in the php.ini so
that's where i will look next.
I wish i could find some errors, but even setting debugging on for
rtgui doesn't seem to show any errors.
if anyone thinks they can fix it i can easily set up a clone of this
server for them to try.
