Wordpress Plugin Slider Revolution Error

Question

I am unable to get rid of this following error. The error shows up after I activate the plugin.

Slider Revolution error: could not unzip into the revslider/public/assets/ folder, please make sure that this folder is writable. 

I did chmod 777 to revslider/public/assets/ but with no use.

I also got this error in browser..

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:
    1. In the Slider Settings -> Troubleshooting set option: Put JS Includes To Body option to true.
    2. Find the double jquery.js include and remove it.

I cannot go to Troubleshooting set option after going to slider settings as none of the links (including 'Problem Handlings') work on the right hand side (attached the screenshot)

Answer 1

There is the best solution :

1. List item
2. Go to revolution slider on the dashboard
3. Select your slider causing the problem
4. go to param slider
5. Scroll to problem handlings on the right
6. Select Troubleshooting
7. set option: Put JS Includes To Bodyoption to true.

That's it

Answer 2

I found this happening today after updating the Autoptimize plugin. Turning off Javascript optimisation in the Autoptimize settings fixed the problem (though likely at the cost of some performance).
