Probably a php issue but maybe not, error reporting

Hi All,

I have 2 sites configured in my Nginx configuration (i.e. two server
blocks). The sites each point to a different root directory but run
through
the same php-fpm process via a fastcgi_pass. PHP script errrors are
reporting via the nginx error log, they are also reporting via the php
error
log file (configured in php.ini) on site1.

PHP errors on site2 are not reporting via the php error log file. Any
suggestions?

Thanks

Please provide nginx, php-fpm and php configs.
