How can I customize the "Fatal Error" screen?
You can configure CiviCRM to use a customized "fatal error" screen by following the steps below. You may want to include specific site administrator contact information or other problem resolution instructions on the screen, as well as "theme" it for a more professional or consistent look.


Save a copy of civicrm/templates/CRM/error.tpl
Edit the text and layout of this file as desired. You can add site administrator contact info, site logos, etc. as needed.
Login (with Admin CiviCRM rights) and navigate to Administer » System Settings » Debugging and Error Handling
Replace the default value (CRM/error.tpl) with the relative path (from civicrm/templates) and name of your new file.
Save your changes.


You can also configure CiviCRM to use a custom error handler by referencing a custom PHP function in Administer » System Settings » Debugging and Error Handling
