1. Download the latest version of Slider Revolution

2. Replace the plugin files via FTP

  • Next, delete the folders/files located inside the following directory:
  • wp-content/plugins/revslider/

And then replace them with the folders/files located inside the “revslider” folder that can be found inside the zip file you downloaded from CodeCanyon.

3. Finally, reload the plugin’s main admin page, the “Installed Version” should now match the “Latest Available Version”
