Hi there,
Thanks for emailing support and sorry you are having issues.
I was able to get to proceed to check screen as seen in the screenshot.
Not sure if this is resolved, but if you are still having issues… to get you started on troubleshooting: First, please make sure you are using the most current versions of all of our plugins. You can also try reinstalling them by following these instructions. If that doesn’t help, the next step in troubleshooting this is going to be testing for conflicts with your theme and other plugins (with WP_DEBUG enabled). If you need a testing environment, the free WP Staging plugin will let you create a quick copy of your live site that you can use for testing.
Let me know what you find.
Thanks,
Brendan
