Can’t click pictures AND Menu not working on Mobile

The menu won’t work on my site when I used my phone. It won’t open at all. I’m not sure what’s going on but I like the theme and I want to keep using it. Is there a fix for this?

Secondly people often click the featured picture on web pages but the picture isn’t clickable at all. That would be an awesome change
