I spent all of last night looking for an answer for this question rather than ask but nothing I found worked.
My host (who is terrible and I am switching off of) deleted my ENTIRE blog yesterday and then built it back from cached pages from scratch. Only thing is he didn't set up my Atahualpa correctly.
That is the link. I cannot figure out how to get my header image to fill the entire top (like not have white sides) but I used to have it like that.
When I first signed into filezilla after he restored the site, I went to public_html/wp-content/themes/atahualpa344/images/header folder and there were a bunch of images in there. Per instructions, I deleted all images and put only the one I wanted. When I have one image in the header part nothing comes up. I only get this image when I put three different copies of the header in the folder.
Then I changed the min and max in the style tab (as suggested by Juggledad in a post) but it is not working. Please advise. I think maybe its padding but not sure. Any help is much appreciated!!!
