So I have been wrestling with this problem for a while now. Most times, but not every time, when someone clicks on the All Threads link in hyperkitty, a 500 error is generated.
I googled it, obviously, and at first I thought it was related to this issue, but that has not proven to be the case:
https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/V... <https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/V...>
I’ve attached a “backtrace” below.
The archives were imported from a previous mm3 install a couple of months ago. The problem occurs even with a list state full of immediately recent posts.
Anyone have thoughts on how I can fix this?
