I’ve been working on the staging version of a website for a bit, and now that I’ve pushed it live, my custom post type “Portfolio” archive page, along with all the individual portfolio pages are no longer showing up. They were perfectly fine on the staging version. Any ideas why this could be?
go to Settings > Permalinks and Click Save Changes – this will regenerate the permalinks.
It may take a few goes. But try that, clear your caches and recheck those pages.
