I used a responsive design website layout but when viewed on the mobile phone it uses the mobile layout instead of the full website layout. Is there a way to default it to the full website version for the mobile phone
Sight is a responsive width theme. Responsive width means the layout adapts depending on the size of the device being used to view your site. When responsive width themes are viewed on mobiles sidebars appear below the posts in order to provide as much space as possible for reading.
Go here > Appearance > Mobile and disable the mobile theme.
