Hello,
In order to upload the demo content, all the plugins related to the theme should be installed and activated. Navigate to WoodMart > Pre-Built Websites and the demo: https://xtemos.com/docs-topic/installation-process/
If the demo is not working. 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, share the valid WP login details of your site and tell us which demo you want to import so I can check and import the demo on your site.
Best Regards,
.
