Have a server running nginx 1.6.3 and php 5.5.23 configured with FPM/FastCGI. Nginx, php and mysql were upgraded a couple of weeks ago.
Everything was working until the upgrade. It now seems that I am getting an error when trying to upload a picture and it seems to be a permissions error? the error that I am getting is FastCGI sent in stderr: "Unable to open primary script: (No such file or directory)".
