Blank page when beginning web-based portion of installation

Question:

After running install.sh, I am instructed to launch Centova Cast in a web browser to complete the installation. When I do so, all I see is a blank page. How do I fix this?

Answer:

This virtually always means one of two things:

  1. PHP is encountering an error, but you have configured PHP not to display error messages. Ask your systems administrator to edit php.ini, turn on the error_reporting and display_errors settings, and restart Apache. Then reload the web page to see what the error messages are.

  2. Apache is crashing with a segmentation fault. Usually (but not always) you can confirm this by checking your master Apache error log (often /var/log/httpd/error.log or /usr/local/apache/logs/error_log) and looking for a line that says something in regard to "Segmentation fault" or "SIGSEGV".

    This indicates a fundamental problem with your Apache/PHP installation (usually a library conflict of some sort) and because it could be caused by any number of problems, there is no "standard" approach to resolving it. You will need to ask your systems administrator to diagnose and resolve this problem.

Neither of these issues are directly related to Centova Cast (they are both Apache/PHP issues), but once you resolve them, you should be able to see the Centova Cast installation page.
