Apt upgraded openssl and nginx mainline = problems

Hi,

Here is the solution.

Edit your nginx.conf file located at /etc/nginx/nginx.conf and either comment or delete the ssl settings lines or delete them and save the file.

Open /etc/nginx/common/wpfc-php7.conf file and either comment or delete these lines as below:

location ~ /purge(/.*) {
fastcgi_cache_purge WORDPRESS "$scheme$request_method$host$1";
access_log off;
}

Lastly do not forget to reload or restart nginx.
