referred to by most members of the Drupal community as the White Screen of Death or WSOD. There are several reasons why this might occur, and therefore several possible solutions to the issue. (Note: The suggestions on this page might solve the problem even when you do not get the WSOD as it relates to an Internal Server Error.) "Invisible" Errors If error reporting disable error reporting php is turned off, you could be getting a fatal error but not seeing it. On a production site, it is common to have error reporting turned off. If that is the case and PHP has hit an unrecoverable error, neither an error nor content will be displayed, therefore you end up with a completely blank page. What you can do about this is either turn on PHP error reporting so it displays a message on the page itself, or check your log files (from the server) to look for the error. How to do both of these are explained below. Enable Error Reporting Although it may be turned off on commercial hosts and production sites (for good reason, so that users do not see the errors), these errors are one of your best tools for troubleshooting. To enable error reporting, temporarily edit your index.php file (normally located in your root directory) directly after the first opening PHP tag (do not edit the actual file info!) to add the following:

If https://www.drupal.org/taxonomy/term/40718 you want page error messages that are a little more user-friendly, Drupal allows you to customize them. Create two nodes, one for each kind of page error (403 and 404). Determine the ID number of the node you wish to redirect users to. One way to determine the node's ID number is to visit the node and look at the number after the last slash in your browser's address bar. This is your node's ID number. Now enter the paths to your nodes in the appropriate boxes on your error reporting settings page. For example, if the node ID number for 403 error codes is "83," you would type "node/83" into the "Default 403 (access denied) page" setting. Drupal 6 mysite.com/admin/settings/error-reporting Drupal 7 mysite.com/admin/config/system/site-information Because you are creating nodes, they will show up in the tracker and popular content blocks and anywhere else real nodes would be display. If this isn't acceptable, there is a contributed module called Custom Error that avoids this problem.

Better error messages, full syntax highlighting, code snippets and works https://pantheon.io/docs/php-errors/ for AJAX too! Requirements PHP 5.3+ PHP Error Library Installation Download the php_error module Place it in the folder /sites/all/modules of your Drupal site. Download/save the PHP Error error reporting Library, it's just one file. Create the folder php_error in /sites/all/libraries and place/save the php_error.php library file in it (the full path should look like /sites/all/libraries/php_error/php_error.php). Enable the PHP Error module at /admin/modules Configure the PHP Error module at /admin/config/development/php_error Features Errors displayed in the browser for normal and AJAX requests. AJAX requests are paused, php error reporting allowing you to automatically re-run them. Makes errors as strict as possible (encourages code quality, and tends to improve performance). Code snippets across the whole stack trace. Provides more information (such as full function signatures). Fixes some error messages which are just plain wrong. Syntax highlighting. Looks pretty! Advanced Features Customization. Manually turn it on and off. Run specific sections without error reporting Ignore files allowing you to avoid highlighting code in your stack trace. Application files; these are prioritized when an error strikes!

Tags: Code, Debug There are three basic kinds of PHP errors: Notice: room for improvement; typically unset variables or missing array keys. Warning: errors will probably occur if not addressed. Error: fatal, execution terminated. Often known as the "white screen of death". For more in-depth information, see Error Handling and Logging. Each of the PHP errors are handled differently depending on the site environment. On Dev, they are shown directly to the user in the browser. On Test and Live, PHP errors are not displayed to users, but they'll still be logged. Notices and warnings are logged in the database logs if db\_log is enabled for Drupal. The PHP constants WP_DEBUG and WP_DEBUG_LOG can be enabled for WordPress to save errors to wp-content/debug.log. PHP errors are also logged on the application server at logs/php-error.log. Here's a breakdown of what errors are shown and where: Environment Severity Browser Watchdog logs/php-error.log Dev notice Y Y N warning Y Y N error Y N Y Test notice N Y N warning N Y N error N N Y Live notice N Y N warning N Y N error N N Y To learn more about PHP error logs, see Log Files on Pantheon. PHP Errors Slow Down a Site An error, no matter what severity, is a problem that needs to be addressed. Any PHP error, even a notice, will drastically reduce the speed of PHP execution. Even if you don't see the error in your browser, and even if you explicitly disable logging, every single PHP error will slow your site down. If database logging is enabled, your site will be even slower, requiring a database write for every error. However, disabling logging does not address the problem, it only hides the symptom. Best practice is to fix every notice, warning, and error as you discover them. If they're in an extension (WordPress plugin or Drupal module), roll a patch and submit it to the project's issue queue. See http://stackoverflow.com/a/1869185 for some more details, including benchmarks that compare the differences between suppressing notices and actually eliminating the root cause. PHP Unhandled Exceptions on Pantheon A PHP exception is a mechanism for defining error conditions and how to handle them. For more details on Exceptions, see the PHP documentation on Exceptions.. PHP Exceptions are errors, and depending on the severity and whether they are handled correctly can crash your site. As Except
