shuffman I'm having this same issue but not finding the php log file you are talking about,, can you give me a few steps on where to find the logs to view if I too have the same error in php.ini?
You should really start your own thread with your environment information.
That being said where your log files are are totally dependent on the OS you are running, and what you have the location set to in your config files.
You can create a file in your root osTicket folder (lets call it test.php)
in the file put <?php phpinfo(); ?>
save the file.
Open the file in a web browser (yoursite/test.php)
error_log is ilsted on the resulting page and will tell you where the PHP error logs are stored on your server.
