Generatepress theme have settings for managing page layout.
but https://www.onbiz.com/places/ is not a page.
it is just using content of GD Archive template page. but originally it’s an archive of a Post type gd_place
So far I have explored. In Generatepress theme, there is no way to set Layout for particular Post Type except for blog archive.
So I have set blog archive sidebar layout in customiser. Seems good for places. since it is the only way to set layout for archive in theme. it will be standards for all archive those using blog layout.
Generatepress theme picking blog layout for search page. and since blog layout have setting for column size. it is the cause of issue.
