I have customised the Twenty Thirteen wordpress theme with a child theme but the mobile menu does not expand when pressed. I have removed all the styles from the child theme to see if anything I have implemented was causing the issue but even with the styles of the parent Twenty Thirteen theme the mobile menu does not expand. I have deactivated all plugins and again this did not help. Could really use some help with this as I am at a loss.
