Hi, whenever i upload the header image to the theme, the left side and the right side of the image will become transparent. May I know how to change it to normal ?

Thanks in advance

Go to Atahualpa Theme Options (ATO) > Header Image. There you can adjust the width and level of opacity to remove the effect.

thank you very much.
