pagina vuota example.com/phpmyadmin con errori nella console del browser

Ho installato phpmyadmin e l'ho collegato simbolicamente sul mio server LEMP (php 7). Ma quando vado a nome host / phpmyadmin, viene restituita una pagina vuota con l'icona phpmyadmin sulla barra del titolo.

E 3 errori nella console del browser:

Impossibile caricare la risorsa: net :: ERR_INCOMPLETE_CHUNKED_ENCODING

Errore di riferimento non rilevato: $ non è definito

Errore di riferimento non rilevato: PMA_commonParams non è definito

Ho provato molte soluzioni ma non sono riuscito a trovare qual è il problema :(

configurazione del server:

         server {
   # listen 80 ;
   # listen [::]:80 default_server;

    # SSL configuration
    #
     listen 443 ssl default_server;
     listen [::]:443 ssl default_server;
    #
    # Note: You should disable gzip for SSL traffic.

PHP-FPM in nginx: il buffer di fastcgi non è abbastanza grande.

Prova ad aggiungere questo alla tua configurazione:

fastcgi_buffers 8 512k;
fastcgi_buffer_size 256k;
fastcgi_send_timeout 5m;
fastcgi_read_timeout 5m;
fastcgi_connect_timeout 5m;

La mia configurazione nginx:

server {
    client_max_body_size 100M;

    listen 80;

    server_name phpmyadmin.dev;

    root /usr/share/phpmyadmin;

    access_log off;

    index index.php index.html index.htm;

    location ~ ^/(.+\.php)$ {
        try_files $uri = 404;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include /etc/nginx/fastcgi_params;

        fastcgi_buffers 8 512k;
        fastcgi_buffer_size 256k;
        fastcgi_send_timeout 5m;
        fastcgi_read_timeout 5m;
        fastcgi_connect_timeout 5m;
    }
}
