I'm trying to put some code in the <head> portion of a website, and have been using the "Enhanced Header / Footer Injections" plugin to do it easily. It had been working well until I created a blog page rather than a static page. I can edit the header.php file found in the theme folder, but any edits I do there only show up on static pages. It seems that blog pages use a totally different file (or maybe it's just a condition that is set somewhere?) to show the header. What can I do about this?
