Hello,
Thank you for reaching out. The issue is that the demo content might not have been imported correctly, or some elements were imported in a different format than expected.
Please try to deactivate the third-party plugins and import the demo again.
Note that our dummy content works only on a fresh installation. If you have some content already it will conflict with your existing posts and most of the content will not be imported correctly.
If the issue remains, try to Increase the “PHP Max Input Vars” parameter to 10000 or higher in your PHP configuration and import the demo again.
If the issue still remains let us know I will check and import the demo on your site.
Best Regards,
.
