Theme used on an inhouse intranet system – will never be public. Cant give u access to localhost.
The widget I am using in the standard Archives WP widget – there are no settings to check.
What do I check for with developer tools? I can see that the Archives for the month are not showing the default template page for the archives – there is no sidebar. A normal post uses the exact same template and there is a sidebar automatically.
My default for blog is set to right sidebar and grid. The posts are in grid format but no sidebar when viewing archives.
I got around this problem for categories by creating a page with a shortcode for a single category – but I cannot do that with the posts archives for the months.
