Mobile navigation not working

Hello

I have two problems;

First; my site (pestcontrol-at-home.com) navigation is not working on android and windows mobile devices. I have not been able to test on iOS yet. It was working previously and I’m not aware of changing any settings that would have made it change. I have tried turning off “responsive design” and re-selecting but it didn’t make any difference.

Second; when navigation did work, the alignment was all off. After tapping the nav box, the menu screen would slide to the left leaving only the right half of the menu screen and the right-side border visible. This happened regardless of the orientation of the mobile device, i.e. landscape or portrait.

If anyone knows what my problem is, I would be most grateful to hear from you.
