wordpress Customize not working and I can not publish the article

Question

i have installed wordpress with nginx and mariadb. The installation is fine but in my admin panel I can not publish article or page and publish button customize menu does not work. here is my nginx configuration file:

server {
listen 80;
listen [::]:80;
root /var/www/wordpress;
index  index.php index.html index.htm;
server_name  word.exemple.com www.word.word.com;

 client_max_body_size 100M;

location / {
    try_files $uri $uri/ /index.php?$args;        
}

location ~ \.php$ {
include    /etc/nginx/fastcgi_params;
fastcgi_pass             unix:/var/run/php/php7.3-fpm.sock;
fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}

I changed the rights of the wordpress folder, so that it belongs to www-data: www-data. if anyone has an idea thank you in advance.
