Stylesheet not parsed because non CSS MIME types are not allowed in strict mode
I see message: "No input file specified." for all links:http://test.opendialogueapproach.co.uk/wp-content/plugins/revslider/public/assets/css/settings.csshttp://test.opendialogueapproach.co.uk/wp-content/http://test.opendialogueapproach.co.uk/wp-content/plugins/revslider/
Seems like you Site conf file is incorrect. Probably file does not exist in /var/www/opendialogueapproach.co.uk/test/html/wp-content/plugins/revslider/public/assets/css/settings.css
I think you should correct root in your config, or upload files to the /var/www/opendialogueapproach.co.uk/test/html
I have got this error when I put the authentication auth_basic in Nginx. So I have to skip the authentication in the folder of assets.
location / { auth_basic "Restricted Content"; auth_basic_user_file /etc/nginx/.htpasswd;}location ^~ /assets/ { auth_basic off; gzip_static on; expires max; add_header Cache-Control public;}
