We recently purchased this template and started to configure it. In Home Page - all section, we have created the section for front page (Home page template) and Slider with "Use section for Slider", the problem is that it does not allow adding images, I click on the button but it does not do any action.
I wait your promt response, a cordial greeting!
Please try to install and activate this plugin, and see if it works: https://wordpress.org/plugins/enable-jquery-migrate-helper/
