PHP fun

Sometimes PHP is a pain. no, kinda always a pain.

when you update PHP on your server and everything falls over, theme breaks, etc, you can roll back the php-fpm socket temporarily by editing the sites-available conf in nginx. Apache2 is a little different. 

xxxxxxxxxx

sudo vim /etc/nginx/sites-available/default

Change the FastCGI backend to use the new (or old version) PHP-FPM socket, save and exit the file

xxxxxxxxxx

location ~ \.php$ {

        include snippets/fastcgi-php.conf;

        fastcgi_pass unix:/run/php/php7.2-fpm.sock;

}

Run the configuration test

xxxxxxxxxx

$ nginx -t

​

Restart the web server

xxxxxxxxxx

$ sudo service nginx restart

see if that gets you going long enough to figure out why php is breaking your site.
