Slider not showing after Free Chronicle Theme Updated

Hi. The site was working fine. I then updated the free chronicle them to version 2.7. I also update wordpress to version 5.2.3.

The slider is slider 2 and has three images.

The slider was working as it should before the updates.

Now the page with the slider on (which is the themes page) shows but without the slider being displayed in any shape or form. No text, no buttons, no images.

Is there something obvious I am missing? I’ve looked on the forum but I can’t find anything on it. I’ve seen and reviewed what to do if it doesn’t auto play and the .js file mentioned in the other post looks as it should be.

To recap: before updates slider present and working
update theme and then wordpress
Now the slider has disappeared.

Any thoughts gratefully received.
