Hello,
I do not see that Slider revolution plugin is activated on your site http://prntscr.com/pwf552 It is because of access restriction or this plugin is deactivated?
We are support team, do not hesitate to set the administrator role for the user.
You can import the slider manually, just download XStore import files from this page https://www.8theme.com/downloads/, find a folder with the desired demo inside and archive of the slider > go to slider revolution and import slider.zip.
Regards
