Mobile version shows code.

My site is https://www.dirtylaundryreview.com … the site is very much under construction, but I’m having trouble when viewing on a mobile device.

On a mobile, it just shows a bunch of code, but when you choose to “view full site” it corrects itself.

I’m running Creativo 4.0 theme… I did a support chat with my host who said “you will need to add the dns records for a mobile site. you can do that in the dns records…”

I admit I am quite naïve. I am new to this whole thing, trying to learn as I go. I’ve been looking around trying to find some guidance with this. I appreciate any help.
