I am trying to set a custom template for my blog posts page using the Template box on the Page Attributes section of the page.
However, the template does not get used on the site.
Is there a certain reason why or maybe a special process I need to go through to get a custom template to be used for the blog posts? Could it be the theme is overriding the custom page somehow?
Structurally the template is fine and appears as one of the template selections in the pulldown box.
Here are screen shots:
This is from Settings
This is from the "Blog" Page Attributes:
post
post type doesn't normally have the templates meta box that thepage
post type has. Can you verify this isn't something added by the particular theme you're using? See the Template Hierarchy page to see how WordPress loads templates, note that posts don't have the custom template entry that pages have.
