No worries, this issue have a very simple fix. You just need to install and activate Slider Revolution plugin under Admin sidebar > Appearance > Install plugins.
Oh, then it looks like that the Slider Revolution content didn’t import correctly.
The issue can be easily fixed by installing the missing content. We can attach the file for download here and you can import it manually or if you want we can install it for you.
Thanks for helping me! If it just only downloads and installs the missing content. Could you send a download link? But if it’s more complicated than I thought, mind you can help me
