Moving a single or multiple posts of a thread into another thread located in another category results in http 500 error. I tested with both a moderator and admin account and with both a single post or multiple selected posts. Permission matrix of the categories:
Category
Group
Permissions
Source
anybody
see
Source
group01
see reply create
Target
group01
see reply create
Note that we have we have a separate permission group for mods and admins and I assume that the root cause is some tricky permissions issue. Ideas how to debug this are welcome
Update: The source catogory in federated (ActivityPub), maybe this plugin code plays a role too… I removed the separate permission groups for mods and admins and tested again with two accounts which have “standard” mod (Moderator = Yes) or admin (Admin = Yes) permissions. Same results: The error 500 appears for any use case: new topic, existing topic, new message.
Note: This bug was already reported a few times earlier and there were already some code fixes. I see it again in our instance with the current release 2026.3.0-latest
I would guess that the root cause lies somewhere behind, e.g. in the database request from postgres (we use separate containers and a dedicated postgres server)
