I was getting the same result in the server buffer as I was in the groups buffer: broken groups (there turned out to be a few) couldn't be entered. But deleting the active parameter did the trick. (I'd also never tried "G c" before, that was fairly impressive. I'm not really comfortable with customize, and will probably stick to "G p", but still, impressive.) I deleted the active list for the broken groups, restarted Gnus, and all was well. I'm trying to learn more of the Gnus internals, and feel like I've made some progress, but I have to say the "active list" stuff still feels like voodoo to me. There's no way in hell I would have touched those entries without your prompting (and a fairly unimportant broken group to test on). There's a fragility to the whole thing that makes me light incense before I look at gnus-active-hashtb, or ~/.newsrc.eld. And if Gnus knows enough to tell me it "Can't open group", doesn't it know enough to try recreating the numbers itself? Okay, mini-rant over, sorry. I really appreciate the help. > The latter is most likely to help at all as the problem is likely that > you have confused gnus by switching servers and the IDs of the messages > have changed. > > I assume you are not using the gnus agent. I'm not entirely sure, to be honest! I have configured nothing to do with the agent, but I do use Gnus in unplugged state quite regularly. I guess that counts...
