Hello, @contemsolutions,
Thanks for your contact, and sorry for the inconvenience, but there is no such issue that many customers are facing, but only some and most of the times it relates to the server, try to change the server and test again and if still you will face the same issue then please share your site WP Admin URL and Credentials under the private content area of this topic, and let us know which demo you want to import and with which page builder so that we will try to import it for you on your site.
Best Regards,
PThemes Team.
