For some reason when I view my site on mobile devices the homepage just displays the full article one after the other as opposed to thumbnail and text previews. Any idea what the reason behind this is? Or how I can possibly change how my site looks on mobile devices.
It shows OK on my iPhone. I checked the demo page of this theme (justblue) on my phone and the only major difference I noticed is the non-responsive adsense block on mobile causing some trouble with responsiveness. You can try disabling that block for mobile devices or using a responsive block instead.
