Thanks for the replies
No, I get the white screen for any WordPress URL I try. I get the Nginx 404 if I try to access a non existent page.
There are no errors in the site logs under /srv/www/site.net/logs/
I just checked the php5-fpm.log under /var/log and that just has:
[08-Jul-2015 22:45:14] NOTICE: configuration file /etc/php5/fpm/php-fpm.conf test is successful
I’m going to run through the process again with a fresh copy of trellis and see how I get on. I must have overlooked something. Thanks…
