# Revision history [back]

The problem is due to changes in the html5lib, it's version was bumped about a week ago. In askbot source code I've changed the version requirement as html5lib==0.90.

If you have already installed the newer version, uninstall it and install an older one:

pip uninstall html5lib
pip install html5lib==0.90


Looks to me as a bug in the html5lib...
