Hidden and not very informative error messages

The bug, step-by-step.

virtualenv env
source env/bin/activate
pip install djangocms-installer==0.9.7
djangocms mysite
cd mysite
./manage.py runserver # connect admin/admin

Create a Page, Add a snippet to Page with content:

It is {% now "jS F Y H:i" %}

As expected, the date is displayed: "It is 21st September 2017 09:57"

Replace the snippet content by a faulty one, with n0w instead of now:

It is {% n0w "jS F Y H:i" %}

Now nothing is displayed, but the html page source contains

	<class 'django.template.base.TemplateSyntaxError'>

• this is not an legal html tag
• this is not very informative

Sorry, it was not fully solved. PR #45 was too deeply scrubbed. PR #46 is waiting.
