Installing Piwik 2.16.1 on Ubuntu 14.04.4 LTS. It's my own VPS (with root access). (This is information from https://forum.piwik.org/t/new-install-of-piwik-2-16-1-receive-get-request-to-piwik-php-failed/20115/1)

I am stuck at the System Check page that displays the message above (screen shot below). Here is my installation process:

• SSH into the host
• cd to /var/www
• wget https://builds.piwik.org/piwik.zip
• unzip piwik.zip
• sudo chown -R www-data piwik
• sudo chgrp -R www-data piwik

I then connect to my host in my browser to start the web-based installation. I get to the System Check page and see the 500 Error for Tracker Status with the "GET request to piwik.php failed." message.

I do not have HTTP Authentication or mod_security running on this host (at least, none of the other virtual hosts see these errors.) Further troubleshooting:

• When I browse to my site http://example.com/piwik.php, I get a 500 Server error
• The error.log file contains the message below.
• There is no file named /var/www/piwik/config/config.ini.php (consistent with error.log message below)
• There is a file named /var/www/piwik/config/global.ini.php.

Any thoughts?
