HUB - Demo Import Fails
If you attempted to import an Hub demo and it failed, it is most likely going to be due to low server limits. Please continue reading for more details on how to fix this. If you have duplicate menu items or other duplicate demo content, please read and follow How To Remove Duplicate Demo Content After Import documentation.
Likely Causes For Demo Import Failures
Your PHP memory, max file upload size, and/or PHP time limit is set too low.
Your web host uses process watching software that prevents bulk processing on their web servers.
You have WP Debug enabled, for information on disabling that, see this post in the WordPress codex.
Recommended PHP Limits
If the import fails there will be a notice in a popup letting you know the demo failed to import. There will also be some initial troubleshooting suggestions letting you know where to look first to resolve the problem. You'll want to ensure you have at least the below PHP limits for the import to complete. These values can be checked on the System Status page.
Hub System Status
Contact your hosting provider and request they increase the limit(s) to the recommended value(s), then try the demo import again.
