I suddenly can't start may Django server any more, running check:

python manage.py check

    from html5lib.filters.base import Filter
ImportError: No module named base

Have you any idea?

Answer 1

I think your html5lib is not compatibale with the bleach version. Maybe for some reason you have the latest version of bleach but not the lastest of html5lib. The version bleach 2.0.0 no longer supports html5lib < 0.99999999 (8 9s). Check Backwards incompatible changes

I think you have to install the latest html5lib (9 9s).

pip install html5lib==0.999999999
