I have added extra fields to the user object.
One of the fields I have added was a Skype text field to hold the user's Skype contact information.
The field had a machine name:
Recently we decided to get rid of this field.
After deleting it through the admin UI ( admin/config/people/accounts/fields ) I was no longer able to save a user after editing.
If I did so I would get an error:
EntityMetadataWrapperException: Unknown data property field_contact_information_skype. in EntityStructureWrapper->getPropertyInfo() (line 354 of /home/master/public_html/sites/all/modules/entity/includes/entity.wrapper.inc).
If I go back and add a new text field to the user object and the text field I am adding has the same machine name then I can edit and save a user object (through the Drupal user edit page) without this error happening.
Should I be able to add fields to the user object and delete those fields without unexpected results like this? Does anyone know how I can fix this so I can get rid of that Skype field?
