Hi @sergiodevify,

This is very likely the same issue a lot of people have been having with PHP 8, which is fixed by my PR here:
https://github.com/facebookincubator/Facebook-Pixel-for-Wordpress/pull/32

It has been sitting around for a very long time but has finally been approved and will hopefully get merged in and released soon. In the meantime you can apply the changes in that PR to the plugin yourself on your site.
