Ok, this is going to sound nuts … but I just added another CPT called “Heritage Test” and, again, the same issue with the maps not appearing.
Then, I created another new one called “Parks test”, and, again, used the exact same listing … and the maps worked.
So, so far today, every single time I’ve created a CPT with the word “Heritage” in it, the maps give me a “No Record Found” … but every time I’ve created a CPT without the word “Heritage” in it, the maps work fine.
It is, for some reason, singling out the word “Heritage”. I don’t understand how or why that would be happening, but it is.
Go back into the admin and see for yourself. Every setting is the same for all of the CPTs and categories … but the ones with “Heritage” in the title have broken maps.
