Hello,
We apologize for the issue you are facing with the Import & Export screen being blank and the fatal error on your staging site.
For the blank screen issue, it could be related to a conflict with another plugin or theme. We recommend checking for any plugin conflicts by temporarily disabling other plugins and switching to a default theme to see if the Import & Export screen appears correctly.
Regarding the fatal error when trying to import settings, this could be due to memory exhaustion or a query not completing properly. You might want to check your server’s error logs for more details. If you continue to experience this issue, please reply to this ticket with your site URL so that we can assist you further.
Thank you for raising this concern, and we look forward to helping you resolve it!
