$ grep -r "bleach_whitelist"
karmaworld/apps/notes/sanitizer.py:import bleach_whitelist
karmaworld/apps/notes/sanitizer.py:    allowed_elements = bleach_whitelist.markdown_tags
karmaworld/apps/notes/sanitizer.py:    allowed_elements = bleach_whitelist.generally_xss_safe

Testing in an interpreter, only generally_xss_safe fails.

Looks like generally_xss_safe is in the upstream repo of @yourcelf but has not been pushed to pip?

pip install --upgrade bleach_whitelist fixed the issue.

Collecting bleach-whitelist from https://pypi.python.org/packages/source/b/bleach-whitelist/bleach-whitelist-0.0.7.tar.gz#md5=9bad5e8990408c6ba9189e3c02a3fee5

Not sure why pip -r didn't run the upgrade properly? The requirements.txt file is pretty explicit on the version.

Strange.. I thought pip -r requirements.txt would do upgrading if needed. I know pip install won't upgrade unless you also do pip install --upgrade.
