I have created a page header that works on other pages, but on the blog page it is not visible.
Is it possible to put a header on the blog page?
Thanks
yes, you need to go to Page Headers > Global locations and assign the header to Posts Page (blog).
Note – if you are using the {{post_title}} template tag in your page header, it will not be displayed on the blog. So instead create a new page header and manually add your title e.g <h1>Blog</h1>.
