Hey there,
Thanks for using Caldera Forms. I’m sorry you’re having this issue.
I think you are saying that form submission starts but doesn’t complete. This would typically indicate that your site encountered an error while processing the form. If you could please log errors using the method described in this post — https://calderaforms.com/2016/05/wordpress-debug-logging/ — and if you need help troubleshooting
You should open a support ticket at calderaforms.com/support.
Caldera Forms Pro has most of this error logging built in. When Caldera Forms Pro users submit support requests, the first thing we do is check those logs, if they have the client plugin active we are typically able to help them right away.
Thanks,
