I received this error during spacenook installation

"mysql LOCK TABLES `bx_cnl_cmts` WRITE; error "

Changing the DB engine to INNODB solved it.

Edit the file install/patterns/header.inc.php. Change

define('BX_DATABASE_ENGINE', 'MYISAM'); ///< db engine

To

define('BX_DATABASE_ENGINE', 'INNODB'); ///< db engine

And proceed with the installation.
