I get this when I activate:
YARPP's "consider titles" and "consider bodies" relatedness criteria require your wp_posts table to use the MyISAM storage engine, but the table seems to be using the InnoDB engine. These two options have been disabled.
To restore these features, please update your wp_posts table by executing the following SQL directive: ALTER TABLE
wp_posts ENGINE = MyISAM; . No data will be erased by altering the table's engine, although there are performance implications.
If, despite this check, you are sure that wp_posts is using the MyISAM engine, press this magic button:
When I press this I get 2 popups.
1. The MyISAM check has been overridden. You may now use the "consider titles" and "consider bodies" relatedness criteria.
2. The YARPP database has an error which could not be fixed.Please try manual SQL setup.
What do I do. Don't know SQL setup...
