Hi,
First of all: excellent plugin, and this error I'm reporting doesn't seem to be a dealbreaker in terms of plugin operation. However it is puzzling.
Jan 6 07:26:24 node1 httpd: WordPress database error Key column 'type' doesn't exist in table for query ALTER TABLE wp_bs2ojz_relevanssi ADD INDEX 'typeitem'('type','item') made by require_once('wp-admin/admin.php'), require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), do_action('init\
'), call_user_func_array, relevanssi_check_old_data
This is on 3.1.3, WP3.5, CentOS.
Cheers
Chris
