When I try and choose an image from my media library for my Header image, it asks me to crop it and then publish. When I hit publish the screen stays white and nothing happens. The Header image does not show.
The site in question is: http://proactivecommunitymanagementcom.sites.qwestoffice.net/
This is the URL of the white screen if that helps (it's the same as the cropping screen): http://proactivecommunitymanagementcom.sites.qwestoffice.net/wp-admin/themes.php?page=custom-header&step=3&_wpnonce-custom-header-upload=54d3057e15&file=149
