I just realized after reviewing this issue again that you mentioned you tried rolling back to Gravity Version 18.104.22.168... which is a very old version. Based on that I know what the issue is.
The latest version of Gravity Forms has database related changes that it needs to make. If those changes aren't made, then you will encounter issues similar to what you described (blank emails).
The issue is the database user configured in your wp-config.php file does NOT have the necessary permissions to alter the database and add additional columns to the Gravity Forms tables.
You need to correct the database user configured in your wp-config.php file so that it has the correct permissions to be able to make the necessary database table updates.
How do you know if this is happening to you?
- Go to the Settings page of Gravity Forms (Forms > Settings)
- Once on the Settings page, in the url address bar append &settings to the end of the web site address and hit enter.
For example instead of this:
Change it to this:
That will attempt to execute the setup routine again and if the database changes can't be made, it will return errors directly on the page that will say exactly that.
In the case of @NYTS, who supplied me an admin login to his site, that is exactly what happens. See this screenshot:
In this situation you need to fix the database user so it has the correct permissions. Then after doing so, repeat the steps above and go to the Settings page and append &setup to the end of the URL. This will again re-run the necessary setup and attempt the changes again. If the database user has the correct permissions, the changes will be made and no errors will be displayed.
