If you are seeing a blank page or unusual behaviour, it is likely that there is an error in your PHP code somewhere. To prevent the disclosure of potentially sensitive site data, we have disabled PHP's error display functionality by default. To get it enabled, simply create a file called .htaccess (or edit an existing one, if present) in the same folder as the page in question.
Add the following 2 lines inside the file:
php_value display_errors 1
php_value error_reporting 32767
You will then be able to see any errors that need to be fixed. Please make sure to remove these lines once you are done.
