Those errors are from caldav & cardav.
I have check:

Check if the config.ini in owncloud/data/news/config/config.ini contains useCronUpdates = true
Check if you are using the system cron (Cron) setting on the admin page. AJAX and Web cron will not update feeds
Check if the cronjob exists with crontab -u www-data -e (replace www-data with your httpd user)
Check the file permissions of the cron.php file and if www-data (or whatever your httpd user is called like) can read and execute that script
Check if you can execute the cron with sudo -u www-data php -f owncloud/cron.php (replace www-data with your httpd user)
Check your data/owncloud.log for errors
Check if the cronjob is ever executed by placing an error_log('updating'); in the background job file. If the cronjob runs, there should be an updating log statement in your httpd log.
If there is no updating statement in your logs check if your cronjob is executed by executing a different script
If your cron works fine but owncloud's cronjobs are never executed, file a bug in core

Cron execute fine, he is logged into administration page.

Thx for the help :)
