Would someone mind helping me with a couple mobile issues?

mylifeinfocus

I'm using the Sierra template on my site (www.alicethompsonphotography.com) and the collage landscape setting for my galleries. I noticed last night when viewing my site on my iPhone, the bottom half of the social icons don't appear on my About page. Also the Search feature doesn't work at all (no search results are ever returned, but it works fine on the desktop version).

Has anyone else had this experience? How do I fix both issues?

Thanks in advance for any help.
