I found the error by trying to change php.ini.
root:/etc/php5/fpm# php5-fpm -i | grep "post_max" PHP: syntax error, unexpected '|' in /etc/php5/fpm/php.ini on line 110 post_max_size => 8M => 8M
Line 110 is
109: error_reporting 110: Default Value: E_ALL | ~E_NOTICE
I had it set to E_ALL & ~E_NOTICE but it was erring then as well. Saying unexpected '&'.
