Hello there,

Thank you for writing in.

First you should check if your php resources are configured properly:

max_execution_time = 300;
memory_limit = 128M;
upload_max_filesize = 128M;
post_max_size = 256M;

You should also make sure PHP version on your server is updated. 

5.6 will do the job, but you may use 7 as well.

Also, please note that Revolution Slider files do not import automatically, and you will need to import these slides manually.

First thing you need to make sure you've downloaded correct file from ThemeForest, from themeforest.net find the theme and in download button dropdown, select "All files & documentation".

Then you will need to navigate to Dashboard > Revolution Slider > Import and then browse the folder you've downloaded from ThemeForest and find the Theme Main Files > xml_export > revslider

Also, make sure to navigate to Dashboard > Revolution Slider > Global Settings and set these Grid Sizes that we use in our demos:

If you have any further issue with this, would you mind providing us with login credentials (in Private Reply) and site url, so we can take a closer look?

Please let us know if there's anything else we can do for you!
Thank You,
Kind Regards,
