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

Facing same problem . Though i can do `from html5lib.filters.base import Filter` in django shell but it raises exception while performing actions from webapp. Any idea for this kind of behavior ? – Manuj Rastogi Mar 22 '17 at 07:25
Can you post your Bleach and html5lib versions!?? – Dhia Mar 22 '17 at 07:37
`bleach==2.0.0` and `html5lib==0.999999999` This is working in Django shell but not in webapp at client side – Manuj Rastogi Mar 22 '17 at 07:42
@ManujRastogi make sureyou update also all packages that depends of html5lib (e.g Weasyprint). – Dhia Mar 23 '17 at 08:01
Its updated . Still facing same problem. Its working on my local but not on production. – Manuj Rastogi Mar 23 '17 at 16:07
It just confirm that it's configuration problem in your prod environment, try to clean it and reinstall the packages. – Dhia Mar 23 '17 at 16:09
did it twice . no success as such – Manuj Rastogi Mar 24 '17 at 07:15
