I upgraded my site from Drupal 7 to Backdrop and I get the following error when I try to create a new user account.
EntityStorageException: SQLSTATE[HY000]: General error: 1364 Field 'language' doesn't have a default value in EntityDatabaseStorageController->save() (line 676 of /app/core/modules/entity/entity.controller.inc).
Thank you in advance for any assistance.
I looked at the database and verified that the default value of the language column is not NULL.
I ran this sql command to change the column to be an empty string.
I know directly editing the database is not usually the best approach, but it did fix the error and I can now edit and create users without any issue.
