[vz-users] middleware errors out with "Unknown context: 'middleware.php'"

[Jens Scheidtmann]

Hello Volkszaehler community,

I have set-up volkszaehler.org and vzlogger on a Raspi 3B according to the
documentation in the wiki. I chose to install directly, ie. using the
install.sh scripts. I installed both as services in the Raspi.

I can log random values to the demo server at demo.volkszaehler.org using
vzlogger and they are displayed in the web interface.

BUT when using an appropriate uuid and http://localhost/middleware.php as
middleware, I get the following error message in vzlogger.log:

```

I am at commit 240c882f3cb427d2ad3a1ded200ebb8ceac1e1d5 (HEAD -> master,
origin/master, origin/HEAD) for volkszaehler.org and commit
27eb8d1566ec493d9cf64d2b53676c846ebb6e35 (HEAD -> master, origin/master,
origin/HEAD) for vzlogger.

What could be the cause?
What information do you need in addition?

Thanks in advance, Jens
