My website is stuck in "mobile" format and can't be seen

If you try to see https://www.yobaland.com, you will get a “mobile” version of the page. I cannot change it back to the non-mobile version and I did not change it to “mobile” in the first place.

I can only see my website in normal view in the admin. Is it possible my website has been compromised in some way? I noticed if I put a note on Twitter or Facebook, something that I did not write shows up if I put https://www.yobaland.com in these social sites.

Please help if you can! Thank you.
