Page, Post, and 404 Templates - Module 2-3 - Building a WordPress Classic Theme with Pinegrow

The Page and Post templates we make in this lesson are a piece of cake compared to the Index template and the header/footer. We also create a basic 404 page with a search form to round out our main template package.

Does anyone else get an error when activating "If in_category"? Everything else perfect

[@AdamLoweIO]

What error are you seeing? It’s worked fine in all my projects. You may need to check whether you are testing inside and outside the loop. You can also check the php code to help figure out whether Pinegrow is writing bad code or if the issue is on the WordPress end.

It’s no problem. I’m moving my house today so I don’t have a computer to dig into things too much. It looks like you might be calling the function outside the loop so WordPress doesn’t know the post’s categories in the context of where you are asking it.
