When I go tohttp://DOMAIN/dashboard/users/attributes/edit/ANY_ATTRIBUTE/... and check any of those checkboxes such as "Displayed in public profile" and update the attribute, it doesn't save. I checked if it really displays on the profile page, no it doesn't display. I went back to dashboard to edit the attribute, the checkmark is not even there. Tried again and again, no it doesn't save.
I tried the same on my other website, it is not working there either.

Please see if you guys have the same problem?

Thanks in advance.

Note: I have just updated my website to 5.4.2, and while using 5.4.1.1 I had no problems with that issue.
