I am having issues creating a full width post. I see that amazing theme gamepress which I use has the Full-Width-Page.php which appears to also remove the sidebar which is perfect for what I would like to do. I also found the webtut link below that which shows it is possiable. I tried using the gallery code ["gallery size="full"] on my gallery of Hi-Quality photos but am having issues creating a full width post. Can anyone please explain to me how this is done?
