When I visit https://iplay.firstdynamic.com/whole-baby-guide/category/nourish/, and got there from the link above, I see what appears to be different sections. Ideas, Recipes, Videos, Resources. 2 Posts under each, except for Resources which has one.
The two under “Ideas” lead to working links, both under Recipes lead to 404s and the url doesn’t reflect the Nourish category term, but does for “recipes” as would be expected.
Videos are both fine, and Food Journal is leading to a 404. It seems like some of them are working again, but not quite all of them.
From the looks of the body tag, it is the nourish category archive, but I can’t say for certain what’s going on in the template file it’s choosing for that url.
Would you be willing to provide some information gathered from a custom plugin I did to help me debug CPTUI upgrade issues?
