Site doesn't show with theme

Hi,

my site somehow doesn’t show with the HB Theme like it normally does (see screen capture #1) unless I logged into my wordpress account, but as if it was on mobile (http://www.mentorless.com/2015/09/04/30-piece-of-advice-from-robert-rodriguez-to-lead-a-creative-life/). I’ve tried on both safari and firefox and was made aware of it by readers.

As a consequence, all the titles etc, shows as code in the articles too 🙁

Not sure what to do, any help would be greatly appreciated!

Thanks in advance,
Nathalie
