Windows php.ini File

C:\Program Files\FileMaker\FileMaker Server\Web Publishing\publishing-engine\php

1. Error Log settings - please enable the following highlighted line if this is not currently enabled (you enable this line by removing the leading semi-colon character at the beginning of the line):
