Заменете:
public function supportEngine()
{
$variables = $this->_getConnection()
->fetchPairs('SHOW VARIABLES');
return (!isset($variables['have_innodb']) || $variables['have_innodb'] != 'YES') ? false : true;
}
с това:
public function supportEngine()
{
$variables = $this->_getConnection()
->fetchPairs('SHOW ENGINES');
return (isset($variables['InnoDB']) && $variables['InnoDB'] != 'NO');
}
