Revolution Slider Error: You have some jquery.js library include that comes after the revolution files js include.
This includes make eliminates the revolution slider libraries, and make it not work.
To fix it you can:

In the Slider Settings -> Troubleshooting set option: Put JS Includes To 

Body option to true.

Find the double jquery.js include and remove it.

I go to Slider Settings -> Troubleshooting/Problem Handlings but i can't click them.

Such issues are most often due to plugin conflicts. Try the following:

Deactivate all of your other plugins and then try to adjust your Rev
slider settings.
Ensure you are using the latest WP version.
Ensure your server is running a PHP version 7 or above.
