[MM3-users] Re: Hyperkitty: AttributeError: 'NoneType' object has no attribute 'subject'

Hi Mark,

This may be related to our not clearing cache when deleting messages/threads. See <https://gitlab.com/mailman/hyperkitty/issues/160>;. If so, restarting your web server may help.

I tried restarting uwsgi but no dice. It's only affecting particular threads and I don't know of any threads being deleted so I think it's probably a different issue.

Best wishes

alex
