Website not up to date with Wordpress preview

Hi guys,

Congratulations and thank you for the great work on Shapely!

My website is: http://www.addmetothelist.co.

Something very weird happened! I have updated bouton color, deleted the search bar. This shows when I am connected to my Wordpress session but not when I look at my website on other browsers. On these other browser, the changes I have made show only on the homepage.

Also, how can I delete the footer everywhere?

And, I could not load an image on full background on this page : http://addmetothelist.co/find-a-plus-one/

Thank you for your help. I am really stuck here.

Kind regards,

Sophie
