Missing entries from menu
October 17th, 2014
You can go to the Forms > Settings page and append &setup to the end of the url. The page will reload and it will also display messages if there are any database issues detected.
If no messages are displayed I would recommend enabling WP_DEBUG and WP_DEBUG_LOG and then go to Forms > Entries and see if any errors appear or are added to the log file:http://codex.wordpress.org/Debugging_in_WordPress
