Thank you for taking the time to reply. I already read that post in detail before asking the question and have followed the suggestions. They don’t solve this problem. Set the image size to 1140px, slider size to 1140px, downloaded and run regenerate thumbnails. Slider is still stuck off to the left of the screen. This is not a case of the image not being centered in the slider but the slider itself being flush to the left of the screen. Please take a look at the link if you haven’t already.
To confirm, with Legacy 1.3 as the theme the slider is positioned correctly.
