If you are getting a 404 when trying to visit a post on the front-end it doesn't seem to be a problem with a template you created with Views to display it, but rather with the settings for the post type such as the rewrite settings.
The first thing I would do is edit the post you linked to on the back end, and then check the URL that is shown to view the post on the front end: is it the same as the link you shared?
Maybe the post type settings or permalink settings where changed, and the URL for the posts is no longer the same?
For the purposes of testing, you could
- create a new post type
- publish a test post
- verify that it is visible on the front end
- assuming it is, compare the default post type settings for this post type with those for your show post type which doesn't appear to be working correctly
Could I take a look at your site to get a better look at your settings?
Seems like you have a live site rather than a staging site, so if it is not obvious what the problem is I may take a copy of your site to install locally for testing if that's okay.
I will mark your next reply as private so that I can get log-in credentials from you—you may want to create a temporary admin user for me to use that you can later delete. And be sure to have a current backup of your site.
I logged in, checked the settings for the Shows post type, found the Kendra on Top show you linked to before, verified its URL and content template settings, then checked it on the front end and... it worked fine.
I thought maybe it was an issue about being logged in, so I checked in another browser as a guest, and it also worked fine.
Whatever the issue was it seems to be resolved, if you could please confirm yourself.
Yeah, you are correct. Not sure what happened there. I feel like I had the same sort of success with the other issue I was having with toolset. I don't recall changing anything, but all of a sudden it just started working. Odd. Thanks for your help.
