Since my upgrade from 2.2 to 2.3, I cannot access my dashboard as I am stuck on the upgrade.php page asking to update the database.
I do so and I get this kind of error :
WordPress database error: [Duplicate entry '1' for key 1]
INSERT INTO wp_terms (term_id, name, slug, term_group) VALUES ('1', 'Junkyard', 'general-2', '1')

My blog has been updated, but I have lost all my categories. Any idea how to get past step 1 in the upgrade process ?
