Unable to Delete User

[TonyH]

Greetings,

You might try the suggestions in this post:

Can't delete user due to foreign key restraint

For me when I ran into this error, I just followed what it said, i.e. I deleted the user from coursecreator table first (not sure if thats is the correct name of the table). And then tried to delete it again from User table. (Using Django/Python Shell)

As for your specific error:

@misilot

"Unknown column 'third_party_auth_ltiproviderconfig.visible' in 'field list'"

I recall having this problem (or similar) on our site when trying to delete users who created accounts using the OAuth. Removing linked references to the user might help. Also, searching for and then deleting the third-party auth tokens for the specific user might remove the reference to the unknown column.
