Okay, deactivated all my plugins and the header image resize is now working as it should. I’ll let you know which plugin is the problem when I find out.
Another issue, though, with the page header image. When I set page header to ‘inside content area’ I want the image to fill that content area to the edges, but it doesn’t – there’s white space around it. How can I get the image to fill the content area?
Here’s how it looks presently: http://marandall.com/about/
