After installed this plugin and tried to activate instead of dashboard I got an error message ” …The used table type doesn’t support FULLTEXT indexes…” DO NOT PANIC read below :

If you receive an error like “The YARPP database has an error which could not be fixed.” or “…The used table type doesn’t support FULLTEXT indexes…” after installing YARPP, either your database username does not have access or you need to change your database engine for “wp_posts” from InnoDB to MyISAM.

to solve the aceess problem visit here and try to run SQL manual.

To change the engine goto to myPhpAdmin and select “wp_posts” table>operations->engine.
