Likely Causes For Demo Import Failing
- Your PHP memory, file upload size, and/or execution limits are set too low
- Your web host uses process watching software that prevents bulk processing on their web servers.
Recommended PHP Configuration Limits
If the import stalls and fails to respond after a few minutes, or it fails with an error message, you might be suffering from PHP configuration limits that are set too low to complete the process. You should contact your web host and ask them to increase those limits to a minimum as follows:
The theme and plugins require PHP version 7.0 or higher. Now is the time to think about upgrading to PHP 7.0 if you haven’t already. Not only because you want to be running on supported software, but you are guaranteed performance benefits! If your current WordPress host doesn’t support PHP 7.0 yet, we strongly encourage you to seek out new hosting.
And you can also check your PHP error logs to see the exact error being returned.
