I tested this component out, found it overly complicated to install - why the need for separate cjlib etc? Then decided, after all that it did very little more than core Joomla so uninstalled. It broke and now Joomla core Extensions manager shows :

Fatal error: require_once(): Failed opening required '/home/server/public_html/domain/components/com_cjblog/api.php' (include_path='.:/usr/local/php54/pear') in/home/server/public_html/domain/plugins/content/cjblog/cjblog.php on line 17
