FATAL ERROR with NGINX

Hello, RankMath plugin detected that I was using an NGINX server.
I was asked to add the following code:

# START Nginx Rewrites for Rank Math Sitemaps
rewrite ^/sitemap_index.xml$ /index.php?sitemap=1 last;
rewrite ^/([^/]+?)-sitemap([0-9]+)?.xml$ /index.php?sitemap=$1&sitemap_n=$2 last;
# END Nginx Rewrites for Rank Math Sitemaps

I then asked assistance to my host who installed the code but that to create errors:

2020/06/12 16:17:42 [error] 23828#23828: *142390 FastCGI sent in stderr: “PHP message: PHP Fatal error:  Uncaught Error: Call to undefined function is_cart() in (I hide my site address)/public/wp-content/plugins/seo-by-rank-math/includes/class-post.php:172

My interdmaire pointed out to me maybe a PHP version problem :

Your sites are using the latest stable version of PHP; but the error log I pasted indicates a scripting/coding issue with the plugin itself:
PHP Fatal error:  Uncaught Error: Call to undefined function is_cart() in (I hide my site address)/public/wp-content/plugins/seo-by-rank-math/includes/class-post.php:172

Thank you for your assistance, have a nice day
