Hi Patrick
You should activate the plugins after active the theme then you should import the demo content.
You can use wp reset plugin, clear your content, activate theme, then active the plugins.
After that please import the demo content.
If you still have the issue, provide me your wp admin details via our private content box below..
Thanks

If you see the home page still doesn’t work correctly.
