All users. I just deleted all but the admin user and still get the error. And since all other users are deleted no node assignment or user type issues should be possible.
No language have been updated and no config files have benne renamed.
Hmm, strange! Unfortunately there's a lot going on in the Page_Load event, so it's probably easier if you can get the line # in the stack trace. To do this, try downloading the "Symbol Files" from Codeplex, and drop them in your /bin/ directory. When you revisit the page you should hopefully get some more info that will help lead us to the real problem :)
Stack trace is still the same after dropping the system files in the /bin folder. Made sure debugging was set to true in web.config and then recycled the app pool - no luck :-(.
Is it a database issue perhaps. Tried to delete some obsolete users in the db but they had a reference in to another table other than umbracoUser. I mean - could there be one or more broken relations in the db user tables triggering this error? What does your experience tell you?
Are you sure the stack trace is the same? I just tested (with another exception) and it added the line numbers after I added the symbol files. I linked to the 4.7.2 ones, that's the version you're using right?
It's hard to guess as to what the issue is as there's quite a lot of logic going on in the EditUser Page_Load method. I'm not quite sure about relations, I think the only dependency on umbracoUser is umbracoUser2App, so maybe an application was removed that they have access to -- but I don't think that would cause the issue.
Yes the stack trace is the same. And yes the site is running 4.7.2. So it beats me why I don't get the added line numbers to the stack trace.
In the user section I deleted all but the admin account. In the databse however I still have alle the accounts (all set to userDisabled 1) I managed to delete 2 of the these accounts.
The rest of the accounts throws this error when trying to delete?
Msg 547, Level 16, State 0, Line 2
The DELETE statement conflicted with the REFERENCE constraint "FK_umbracoUser2app_umbracoUser". The conflict occurred in database "s4adb0025", table "dbo.umbracoUser2app", column 'user'.
The statement has been terminated.
But none of them have dependency (or what you call it) on deleted packages in the 'app' column of the umbracouser2app table. Contour was deleted a while ago, and I suspect it to be the culprit.
In between moving the installed 4.7.2 to and from my server and the dev. people (external devs.) I noticed af couple og new/extra languages suddendly appeared in the umbraco/config folder.
All I had to do was to delete the config/ folder content and paste in the 'old' content. (note to others: Don't merge the folders. You have to delete all files and paste in the old ones to make sure all unwanted lang files are deleted).
I had me going with db issues, contour issues a.s.o. - but it turned out to be a stupid little issue with added language xml's.
User section - USer throws error
Hi!
Trying to open a user to idit I get an error:

Can anyone tell what the stack trace points to?
Hi,
Does this happen for all users or only a certain one?
If only a certain user, it's hard to say - was it maybe assigned a start node that no longer exists? Or has it's user type been deleted?
If all users, have you recently updated your language in web.config or otherwise, or renamed any of the /config/lang files?

Hi Tom,
Solved!!
In between moving the installed 4.7.2 to and from my server and the dev. people (external devs.) I noticed af couple og new/extra languages suddendly appeared in the umbraco/config folder.

Awesome - glad you got the bottom of that one :)
is working on a reply...
