So I've updated my server to MySQL 5.6, which supports InnoDB FULLTEXT indices. Unfortunately, InnoDB does NOT support the default delayed MySQL queries that Xenforo uses, and it is still trying to use them to insert data into the xf_search_index table despite having changed the appropriate setting in the Performance section of the Admin CP. I thought perhaps that this setting was being cached somewhere, but it did not change behavior even after restarting the webserver, the MySQL server, and memcached multiple times. Any ideas on why this still won't behave? I've converted the table back to MyISAM for now, but I'd like to change it back if possible.
