We just upgraded to 1.6 and received the following errors from WordPress:
WordPress database error: [Multiple primary key defined]
ALTER TABLE xxxx_rg_lead_detail_long ADD PRIMARY KEY (lead_detail_id)
WordPress database error: [Can't DROP 'lead_detail_key'; check that column/key exists]
DROP INDEX lead_detail_key ON xxxx_rg_lead_detail_long
Warning: Cannot modify header information - headers already sent by (output started at .../wp-includes/wp-db.php:941) in .../wp-includes/pluggable.php on line 934
Is everything going to work correctly? Should we revert our database?
