Portfolio Item page is not showing

The plugin is great.

Everything works, I managed to change the All to Todos (brazilian portuguese word for all) and it really works very well.

Anywayy, I have this problem: when I’m at the portfolio page and click on read more (Leia mais in Brazilian portuguese), it opens a the portfolio item page, but doesn’t show the contents of the portfolio item.

The portfolio page: https://abracerva.com.br/associados/

Portfolio page item: https://abracerva.com.br/portfolio/dum

The portfolio item contents should appear below the menu, I suppose.

I’ve tried to rewrite the rewrite rules, disable and enable the plugin and so on.

I’m using the Infra premium theme, from https://www.orange-themes.com/

Actually, I read all the threads (and found some good solutions for things that I want to change) and I didn’t find a similar problem.

Any thoughts that could be causing this problem?

Thanks in advance.
