Hi Rikard, please see the private original header image file link. The file is being cropped instead of showing the entire image and scaling it down to fit the screen. I show the file width is 1500px yet it loads at 1310px on my screen and the left and right get cut off. Is this a result of Avia, I saw that name mentioned (if i have it correct) in another support post while researching this.

The height of the header area is set to a custom 200px to match the original file. Maybe this is not the best way to do it? Using the large or slim “Header Size” setting causes the same issue plus the main navigation menu does not align under the header background image correctly, it overlaps the header background image. I need the menu below it so it remains visible.

Hopefully that helps.
