Original title: Forum front page inaccessible (blank screen or 404) I am moderator at the SocialHub forum at https://socialhub.activitypub.rocks which is the technology forum for the ActivityPub protocol that drives the Fediverse social realm. Currently there is a 4-day ActivityPub Conference going on, and there has been more activity on the forum than usual. This morning I saw that the main page of the forum, when accessed directly from the URL, shows an entirely blank screen (no html returned). However, deep links such as Spritely Project: The Super Exciting Future Of Fediverse - ActivityPub - SocialHub still work, and give access to other functionality, such as Search and the Admin panel. When clicking the logo in top-left corner, instead of the blank screen, a 404 page is shown instead. I have notified people involved in managing the server, and maybe a server restart is all that is required. But just in case anyone recognizes this as a more serious issue, I would greatly appreciate your feedback, so that we can be up-and-running again in time before the Conference talks commence today. PS. The forum is running v2.6.0.beta1

After disabling discourse-assign: latest works top fails /t/951 still fails Running the query… Ah! You nailed it! {"event_start"=>1601748000, "event_end"=>1601749800, "event_all_day"=>false, "event_timezone"=>"Etc/UTC", "event_rsvp"=>true, "event_going_max"=>100, "event_version"=>1, "event_going"=>[36, 50]} Apparently the events plugin is skipped during merging. But that might be as well because it’s an older version we’re running. Tell me if I can help you test this case. Thank you for solving this @gerhard!

PostReplyKey refers to the reply-to address in emails, it won’t interact with topic list rendering. Checking the stacktrace, it’s failing inside TopicListSerializer dumping, somehow inside lib/instance/public.rb. Try checking the topic featured users list for the old user ID (the set of avatars that shows up on the homepage).

Hi @riking, thank you for responding… AFAIK apart from the PostReplyKey there’s no mention of this missing user id. But it might not be the actual old user id since I do not know that one. How do you think I could find it – or: what should I grep from the logs?

If it is topic featured users, this query should find it: SELECT id FROM topics WHERE featured_user1 = 1234 OR featured_user2 = 1234 OR featured_user3 = 1234 OR featured_user4 = 1234 OR last_post_user_id = 1234

The query returned no result with the old userid, but one topic with the new user id, which is the topic that was already identified as problematic. I moved the topic to another category and indeed the ActivityPub Conference 2020 - SocialHub category is now visible again. Now I guess there’s a reference to the missing user_id 36 somewhere in the data related to topic 951, but I could not find it so far. Or is there another dependency I’m overlooking, wrt user 295?

Do you have a stacktrace for that error?

Nothing more than what I posted in User merge failed, corrupted database entries due to third party plugin - #4 by hellekin and commented after: [immagine] hellekin: I think the problem comes with ActiveRecord::RecordNotFound (Couldn't find all Users with 'id': (36, 50) (found 1 results, but was looking for 2).) The ids match a user account that was merged, but the process seems to have broken…

Oh, I missed the stacktrace in User merge failed, corrupted database entries due to third party plugin - #4 by hellekin. So, it’s failing due to a plugin. I guess one of your plugins stored some kind of user information that hasn’t been merged. Could you give me a list of the installed plugins please?

OK fetching that… I have connectivity issues. I’ll check with safe_mode to see if it works.

(but the rebuild can only happen tonight UTC like midnight) Maybe ping @angus or @merefield for events and locations.

It might be the discourse-assign plugin as it seems to be the only plugin in your list that modifies the TopicQuery class. And I suspect that’s where the error occurs. Can you verify my suspicion by disabling the plugin and checking if the category works? You can re-enable it afterwards. Also, it would be interesting to know if any of the topic’s custom fields references the merged user in some way or another. Can you check that out as well please? ./launcher enter app rails c id_of_problematic_topic = 123 Topic.find(id_of_problematic_topic).custom_fields

You can update the custom field of that topic and remove the non-existent ID. @angus might want to add support for user merging to his plugin. [immagine]Rake task for merging users Plugin authors can hook into the merge process by handling the :merging_users event. I’ve already implemented it for the polls plugin, which merges the votes of the two merged users.
