This feels like something that I should have working. I know I've not been attending to things all that well, so the thing that has happened, that's got us from, "possibly doing nothing," to throwing this error is that I went to update my mail server, and in the update, Mailman3 stopped working entirely (it was a variety of things), but now it's launching, and will load the main web interface... but
Going to any of the list pages, gives the above Error. Well, not exactly the above error, Django is in square brackets. OK, that will work better for me with the how to fix.
How to fix, probably isn't quite what I'm looking for, it's how to diagnose.
The error tells me that the IP address is 127.0.0.1 and that 127.0.0.1 is in the ALLOWED_HOSTS. I *mostly* see this coming from Google, but when I go and look at the webpage, I get:
normal page at /mailman3/lists/
But my lists, all give me...
Something went wrong HTTP error 500: {"title": "500 Internal Server Error"}
I've tried to figure out where to go from here, and right now I'm not making any progress, so I thought I'd ask here.
