What’s the post type slug that you chose? Have you tried the permalink with pretty permalinks disabled?
Based on the screenshot, the post type slug, aka the name field and first input listed, is concerts. Wanted to make sure it wasn’t potentially something generic-ish that could be conflicting with something else internally for WordPress.
Beyond that, I’m honestly not sure why you’re getting a 404 error without potentially knowing what the actual query is for it.
So, is there anything I can do to make it work?
It’s something related to the query for content, which isn’t anything we have settings for with CPTUI specifically.
As a test, have you tried a different post type to see if the same behavior is happening? I often use movie for a dummy post type for my development time, as an example.
Ok, somehow the issue suddenly vanished and all the posts are showing. I asked Pie Calendar support and they wrote this:
Usually this is caused by permalinks needing to be refreshed. This is common after creating a new CPT. You can go to Settings > Permalinks and re-save them twice and the issue should be resolved.
Br, Dl
Interesting, because we do try to programmatically flush those upon content type save.
Regardless, glad to hear things are showing up now. Let us know if you need anything else.
