I am receiving these messages in my error log:
[09-Apr-2013 20:25:59 UTC] WordPress database error Duplicate entry '19661-84' for key 'PRIMARY' for query INSERT INTO wp_term_relationships (object_id,term_taxonomy_id) VALUES (19661,84) made by shutdown_action_hook, do_action('shutdown'), call_user_func_array, autoblogged->ab_shutdownIntercept, autoblogged->ab_processFeeds, autoblogged->ab_itemAddPost, wp_set_object_terms, W3_Db->insert, W3_DbCache->insert, W3_DbCallUnderlying->insert, W3_Db->insert, W3_DbProcessor->insert, W3_Db->default_insert, W3_Db->query, W3_DbProcessor->query, W3_Db->default_query
Any ideas what I need to do to fix this?
