Hi Movin,
I have made two changes as far as I can remember on the theme files 1) for unclickable slider images and 2)for blog medium images.
Actually I already tried deactivate all plugins and also one by one, but it remains the same. Yes if I switch to desktop version in mobile, the content will be displayed however menu is mess up.
What I want to achieve is, when I view on mobile version, the category content is there because the menu is displayed correctly.
