Single pages without head

Hi everyone, I just made my theme from scratch and it’s all good on my local server, but online with the same plugins and codes, just the single.php, single-review.php and single-guia.php (these 2 custom posts) are broken. All the Head code appears on Body. I tried to get the code from archive.php and paste it on the single.php and the same thing happens, and the archive.php its fine!

I don’t know what to do anymore, the link of my website is: https://malditolag.com.br
and you guys can see the example on single.php on this post https://malditolag.com.br/breath-of-fire-6-saira-para-pc-e-mobile/

Ah I tried to strip all the code on single.php and I just left 2 lines:
<?php get_header(); ?> and <?php get_footer(); ?>
Even with just this, the page breaks :/

Thanks in advice
