I think there is a bug in /modules/boonex/blogs/classes/BxBlogsModule.php [7.0.9]
$aAllowView = $this->oPrivacy->getGroupChooser($this->_iVisitorID,
'bx_blogs', 'view', array(), _t('_bx_blog_privacy_view'));
$aAllowRate = $this->oPrivacy->getGroupChooser($this->_iVisitorID,
'bx_blogs', 'rate', array(), _t('_bx_blog_privacy_rate'));
$aAllowComment = $this->oPrivacy->getGroupChooser($this->_iVisitorID,
'bx_blogs', 'comment', array(), _t('_bx_blog_privacy_comment'));
These lines of code cannot retrieve the default values correctly because bx_blogs is non-existent in sys_privacy_actions. Replacing bx_blogs with blogs solves the problem.
