Iphone 6 how to reset safari view?

I go to this website a lot with my iphone 6 Safari. Just recently I don't know what happened, the display of the site looks different on my iphone than on the computer - it used to be the same. On the computer there are two columns with links to each news item. On my iphone it is one column and I can scroll and expand to see the stuff on the right colunm. There must be something that I set on the explorer view but I'm not sure how to set it back. Any help is appreciated.

Hit the menu at the top left corner of the site and click view desktop version.
