I recently rearranged the order of some older subpages, and in the process lost the parent page that is being used for posts. Any help you can offer is greatly appreciated.
I tried making a new page for posts and that page is blank.
Now I have lost my header image! HELP!!!!
Check what page you have set as blog page under Settings > Reading. While reordering pages is sometimes known to cause issues with the site’s structure, the header image shouldn’t just disappear like that, this probably has some other cause.
