Question:
Compress command fails on fresh installation of WireCloud

Description:
I cannot set up a basic wirecloud instance anymore. I tried to create a minimum Wirecloud instance like this:

virtualenv venv
source venv/bin/activate
pip install wirecloud
wirecloud-admin startproject prj
cd prj/
python manage.py collectstatic
python manage.py compress --force

Upon the call to compress the static files an error is thrown:

CommandError: An error occurred during rendering /opt/wc/venv/local/lib/python2.7/site-packages/wirecloud/defaulttheme/templates/wirecloud/views/base_plain.html: Error parsing expression at 30:

What is the problem here? I just set up the most basic Wirecloud instance possible. If I do not compress it the same error gets thrown in the browser. Is the latest release of wirecloud broken? Or is it something else?

What do I need to do to get a running version again? Help would be much appreciated since the docker image seems to not be able to get restarted and configurations like other databases and so on are thus not very easy to set up...
