Hello,
the config file is utterly wrong. If you don't use any extension, you need to comment out all the lines of the [EXTENSION_1] block, not just the [EXTENSION_1] line. The syntax of this config file is based on the INI file. That means the active lines of the config where assigned to the [NEURON_1] block, thus resulting in unexpectable behaviour.
