NSFW Tag Archives Are Empty

First things first, my website is NSFW and adult orientated.

Here’s the page: https://ratedp.net/redesign/tag/femdom/
Theme created with lubith.com

It’s definitely a theme-related problem, because when I switch themes the posts show under the tags.

I’ve tried renaming archive and tag.php, it doesn’t work.

Not sure what else to try.
