navbar-toggler button does not open when openning by iphone

Hi,

I found an issue with your theme about navbar-toggler button.

When opening your site template (https://wowthemesnet.github.io/affiliates-jekyll-theme/) on iPhone, clicking on Menu button does not show dropdown.

I can see this issue happens on iPhone 6sPlus, iPhone X...

But does not happen with responsive mode in web developer tools.
