 * I’m hoping somebody may know what this is. In my site’s error log I get this 
   appearing every 1-5 seconds and as you can imagine it’s building up a pretty 
   huge error log that I have to delete every week otherwise it’s mammoth!
 * [13-Oct-2011 14:57:16] WordPress database error Duplicate key name ‘upost’ for
   query ALTER TABLE wp_epo_order ADD UNIQUE KEY upost (post_id, epo_term_id) made
   by require, require_once, require_once, require_once, do_action, call_user_func_array,
   epo_db_update, epo_install, dbDelta
 * epo_order is a plugin I’m using called [Easy Post Order](http://wordpress.org/extend/plugins/easy-post-order/)
   but I’ve no idea what would be causing this.
 * Any ideas, help or resolutions would be very much appreciated.
