Did you have tried this:
Deactivate other plugins and switch your theme to twentytwelve, and test again
I suspect there is some compatible issue in your theme/plugin
Could you enable WP debug mode, repeat actions you mentioned above, and post the debug log here.

PHP Debugging
In case you think that Types or Views are doing something wrong (what we call a bug), you should enable PHP error logging. Again, edit your wp-config.php file and add the following:
ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
This will produce a file called ‘error_log.txt’ in your WordPress root
