Nivo Slider jQuery plugin Not installed I´m trying to install Nivo Slider to my website. I was following this tutorial from the official plugin website.

I have the folder "all" an inside it I have "libraries", "modules", and "themes". I extracted the FlexSlider-master.zip in my libraries folder, and rename it to "nivo-slider".

The second step was install the extension from the url drupal/project/nivo_slide without drush, download the folder an upload to my server in modules/.

I have clear the cache but the problem persist.

Can someone help me? I can´t upload pictures or links with less than 10 reputation.
If it's drupal 8, which sounds like it, your libraries folder needs to be outside of the sites folder. Where you main Drupal stuff is, like the modules folder. 

ex: Needs to be drupal/libraries and not drupal/sites/libraries

The drupal/sites/libraries is only for Drupal 7.
