Hello,

I have test your slider revolution and it is not working fine. Even I am not able to add new slider or edit the existing sliders. It displays a black screen and showing some JS errors.

It seems that the plugin is not installed properly or some files are missing while installing it. Kindly deactivate the plugin and then delete the plugin and then install and activate it again. This might fix the issue.

Best Regards.
