PHP not working

After I upgraded Ubuntu from 12.04 to 14.04, I couldn't get any sites up. I followed a guide on here to resync ispconfig. That has allowed me to get html pages to work, but PHP pages will not. I get an error: No input file specified.
I'm unable to test my system with the script here: hxxps://www.howtoforge.com/community/threads/please-read-before-posting.58408/
I did check the error logs at /var/log/apache2/ and /var/www/yourdomain.tld/log/
The log for /var/www/yourdomain.tld/log/ was 0kb
I've searched the forums here and google and I'm not sure where to look or what to do next. Please may I have guidance.

Log from /var/log/apache2/
