Hi Emanuel,
Sorry, only one “m” 
As a temporary kludge, I reinstalled python27 in the web application. I tried with a VERY simple example and it seemed to work. Would you mind trying on your side?
On the longer term, Markus has already been working on a more “modern” python version, i.e. 3, of the compilation. We will try to install that in the coming days.
Cheers,
Ralf.
