Hello, @Shantelle,
Still, your provided WP Admin Logins are not correct/working.
And also it seems your site content and demo is broken.
It is recommended to run import on a fresh WordPress installation. For this you can use the WordPress Database Reset plugin https://wordpress.org/plugins/wordpress-database-reset/ The plugin can be used to remove all the existing content and install a new version from scratch.
Please read this article – https://xstore.helpscoutdocs.com/article/60-xstore-theme-requirements Contact your hosting provider to increase mentioned values for your site.
And then try to import the Demo again.
Regards 8Themes Team.
