I’m using a custom user field of type multiselect that’s set to be required for all users. This implies, that it’s also mandatory on signup, i.e., you can’t signup without selecting at least one option from the list.
Instead of showing an error hint, like it’s done for standard fields, the custom user field shows no message if omitted. Signup just does nothing without any feedback to the user.
Furthermore, and I don’t know if this is related, the developer console shows
```plaintext
head_tag_1.js:2 Uncaught ReferenceError: $ is not defined
at head_tag_1.js:2:1
```

Do you have any custom themes or components installed? Are you running latest?

I had the snippet of JS referenced in [Don't Link User Title to a Group](https://meta.discourse.org/t/dont-link-user-title-to-a-group/58267) in the custom code `` theme settings. Unfortunately, I don’t remember if or why I’ve added it in the first place.
Once removed, the error on the console disappears.

Yes, I’ve just updated to latest latest and also don’t see the error hint for the custom user field there.

Can you confirm that you are all set now and the issue has been isolated to some very old, custom code you had in your theme that you’ve now removed? I just want to make absolutely sure there’s not more that needs to be investigated.

No, only the error message I’ve referenced in the last paragraph of my OT is gone now. It was unrelated to the issue I’ve posted above which still holds (but might be a #Contribute > UX issue now)
This is what’s still unresolved:
