Troubleshooting PHP Applications

Browser displays PHP source instead of rendered pages

1

Check that you are using the correct application type by locating your application in the Application list. PHP applications should appear with "Apache/PHP-FPM" as the application type.

If your application is not a "Apache/PHP-FPM" application, then create a new application of the correct type, copy your files into the new application directory, and then edit your site configuration to have it serve the new application.

2

If you are already using the correct "Apache/PHP-FPM" application type then you might be overriding the system PHP handler in your application's .htaccess file.

To check this, inspect the .htaccess file in your application's top-level directory and look for lines mentioning AddHandler or SetHandler, then comment them out by adding a # at the beginning of the line.

For example, if you see this:

SetHandler php72-cgi

... then change it to this:

#SetHandler php72-cgi

Be sure to save the file after making these changes.

Browser displays a blank page instead of rendered pages

1: View the source of the blank page as it may contain partially-rendered code and/or error messages related to the problem.
2: Check your application's error logs in ~/logs/appname as it may contain error messages related to the problem.
3: If your application has a debug mode of operation then activate it and reload the page. This may allow the application to display diagnostic information and/or error messages related to the problem.
