IGMPPROXY Unknown token 'config' in configfile

First I installed the igmpproxy package. This generates a default file /etc/config/igmpproxy.

When testing this configuration file, I receive the error Unknown token ‘config’ in configfile
The config file is the default one generated, without any editing. Reinstalling the package or rebooting the router did not solve the issue.

Someone any idea what I do wrong?

b.t.w. I need igmpproxy for my IPTV (XS4ALL in the Netherlands)

Can you try removing the first line of /etc/config/igmpproxy? The one that says config igmpproxy.

Seems like I am checking the wrong config file. The right command is:
igmpproxy -vvd /etc/igmpproxy.conf

This file is auto generated from /etc/config/igmpproxy after the igmpproxy deamon starts.
