Unable to assign users to topics or posts

AI-generated summary

Users reported an issue where they could not search for other users when assigning them to topics or posts, despite having the necessary permissions. jenmck described a scenario where non-admin users see the assign button but receive “No matches found” when searching by username, even if the user is in the dropdown list. The admin was able to perform searches without issue. Despite extensive troubleshooting involving plugin settings, category permissions, and group configurations, the problem persisted intermittently.

putty suggested this might be related to a previously reported bug from 2024 and asked if console errors were visible during the search attempt. jeffs confirmed experiencing the same behavior, noting that no errors appeared in the console. Ultimately, zogstrip identified the root cause and announced that the issue would be resolved by pull request #44564.

Hello!

I have users with an inability to assign other users to topics that should theoretically have the ability.

These users do see the assign button. However, the list of users is limited to only a couple, and when searching for a username (or name of the user), they get No matches found - even if that user was in the list of users. They are able to assign to users in the dropdown list, if they click on that user’s name directly.

I have admin perms and am able to search for users and assign them.

I have tried:

  • in the Assign plugin settings, adding the groups whose members should be assignable to Assign allowed on groups.
  • in the category’s settings, ensured that the groups are indeed listed in the Additional groups with assignment permission
  • made one of the groups category moderators
  • in each groups settings, for Who can assign this group, I have set to Only group members, moderators, and admins
  • in each groups settings, for Who can see this group's members?, I have set to Group owners, members, and moderators
  • since this is a documentation category, created a test category that’s just a basic discussion category

I’ve reproduced this issue with my test account:

When I click on the `+Assign` button using my test account

When I try to search for my actual account (jen), using my test account

When I try to search for my testing account, using my admin account

Strangely enough, one time my test account and another user were able to successfully search for a user, but the ability went away quickly - I had not changed any settings, since I was still impersonating in my test account. It seems to work one time after clearing cache and reloading. Then it breaks.

I am stumped! Any ideas?

That is very similar to this bug I reported back in 2024. Sharing just in case it’s something that the team has to fix, and this is at least in the ballpark.

Just for giggles, do you see any console errors when you type in the search?

I’m also having this issue. I don’t get any type of error. It just says “No matches found” just like @jenmck screenshot shows (even though the username I an typing in was just showing up as an option for assignment).

thanks for the report @here - the issue will be fixed by
