So with the theme that I have chosen, the plugin is loading the newest available version of libraries. If some jQuery function becomes deprecated from day to day then it may happen. It is loading the newest jQuery from Google’s Content Delivery Network it seems. When WordPress comes already with jQuery.
The problem, for instance right now, with the slider on a secondary page, the images that are to be in the thumbnails at the bottom of the home page do not get shown.
