How do I register a user? I am using Drupal 7.17 and the Services module 7.3.2.

I set the Services module as in the following screenshots.





I followed the documentation on http://drupal.org/node/1447020.

With FireFox HttpRequester, I tried to register a new user.



I got a 500 error.



Do you have any idea?
apparently , there is a field of that name ... and some node / entity which is trying to get saved automatically. Could you have Profile2 installed ?
Did you try the report on admin/reports/fields ?
If you dont find it there, try the database - finde the table that uses the column ie this way :

SELECT * 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME = 'field_published_value'
AND TABLE_SCHEMA = 'yourdb'


i tried on a "default install" and didnt see it :)
