Problems Updating to WordPress 4.9.1

Hi. I’m having problems with Newspaper Theme when I try to update to WordPress 4.9.1. The version of the theme that I have is the last one (8.5). On the one hand, the content of the posts overrun the column of the right (you can see it here http://www.digitalbizmagazine.com/automatizar-el-flujo-del-negocio/). On the other hand, the lightbox of the products don’t work properly (you can see it here http://www.digitalbizmagazine.com/producto/the-next-big-thing/).
Thank you so much for your help.

Hi again. We still have the problems we already describe to you but we have decided to restore the old version of our web in order our clients can see our contents properly.

We still want to update our website so we show to you a capture of the columns issue in order you could help us:

You can still see the lightbox problem in the same direction:

Hello, thanks for your answer, but what about the problem with the lightbox of the products? When you click on a photo of the gallery the lightbox doesn’t work…

Here is an example http://www.digitalbizmagazine.com/producto/the-next-big-thing/

Thank you!
