Where do I go to upgrade the Unite Slider that was packaged with your theme? I have tried to use the Joomla update system, but it does not work. The Unite Slider version that was include is 5.0.8 and the latest version is 5.0.13.
To update Unite Slider, please go to Admin > Extensions > Manage > Install, the upload the extension's package.
If you did the same and nothing works, please add new ticket and send us your admin access. We will help you check.
