So, basically, you reviewed a product without reading the terms or even using the trail.
I had default Portfolios enabled in Settings >> Writing >> Portfolio Projects. It was conflicting with TemplatesNext portfolios. It was creating all kinds of inconsistencies. Now that it’s disabled, TN’s templates seem to be working as expected. Thanks!
Okay, so I just noticed that there are two Portfolio admin panels. Not sure why I missed that before. So it looks like I have to create my projects in the one with the painter’s palette icon for them to show using the shortcode. Is this additional Portfolio control part of the theme? I totally don’t remember creating the “Klingon” project there, but it’s showing in both.
