I’m seeing quite a severe case of this in at least a couple of areas on my forum. (Perhaps in all areas, but it doesn’t seem to affect new topics, so it’s harder to notice in places with more traffic where old topics are pushed out of view anyway.)
This is happening with Discourse v1.8.0.beta4 +95 (although the phpBB import of these posts was done with a slightly early version, but still 1.8.0.beta3 or 4).
For example, this category is largely untouched since I did the recent phpBB import into the new Discourse forum, and as you can see it’s set to show everyone everything:
But when I am logged in with my own account, which has admin rights, about half the posts are hidden from me. If I use incognito mode to browse as an anonymous user, I can see all of the posts:
It looks like the anonymous user can see all the topics that were there originally in the old phpBB forum’s category, but my admin account acts like many of the topics are unlisted.
I can still see the topics if I go to their URLs, with both accounts.
If there’s anything I can do to help debug or fix this, please let me know. I’m new to Ruby but getting up to speed, and fairly comfortable using the Rails console and looking at the database via that or psql, so I’m happy to try technical things.
Ninja edit: In case it’s relevant, just after importing the new forum, I went to each category and selected all topics, then marked them as read. Perhaps something went wrong there?
